Thank you

@pjczc8 I would hope that the white stripe is only on one side. If so, just mount them black walls out. I had some BFG Radial T/A with the raised white lettering on only one side. I had them mounted black lettering out. EDIT: Don't know if you can tell from the photo in my sig, my wife's truck has Radial T/A's black lettering out.

No good deed... ☹️

Nothing special. Just KYB gas. The really silly part is that I HAVE a set of KYB's here already. The plan for them was to put them on my 77 280 as part of a project I have planned for that car. But since I was working on this 240 and running out of time, I figured I would use those KYBs on the 240 and then buy another new pair when I was ready to move forward with the 280 work. So.......... I tear the 240 apart. Break one strut down and get the old cartridge out of it. Open the KYB box I have here, and......... There inside the KYB box is a note. In my own handwriting. I sent the small gland nuts to another Z guy some couple of years ago because I wasn't going to be using them. I need the big ones for the 280 and I didn't own a 240 at the time. The small gland nuts were surplus to me and someone else needed a pair. So I sent them away. Aaaaaaarrrrrghh!!!!!

What are you getting?

Hi, I'm looking for a nice hood for my '72 Z. Anybody got a nice one for sale? I'm located in Seattle, WA. Thanks!! JH

Ahh. This is interesting & helpful. My tip is closer to the red (stock) above. And my corner (1 of them ) is closer to the red one too, although I'm uncovering atleast 1/8 inch of bondo (see pic) Question #2: Does anyone have any info/experience related to the remanufactured steel hoods available on ebay, etc? I see that they're going for anywhere from $800-ish to $1200-ish. I'm considering that as option. Any thoughts, advice, etc? Thnx! JH

Thank you everyone! I really appreciate it 🙏 Message received and I will hunt for best quality 195/70R14s I can get here in Qatar. Although choice is extremely limited. My mechanic recommended these with the white stripe (if I wanted something different) but not sure I have seen any 280z with this type of tire. Has anyone seen 280z with white stripe tires before? Maybe I should stick with period correct Yokohama or Bridgestone black wall tires.

Countdown continues. I'm still waiting for struts. Not ideal. I need to get more miles on this thing to see what else falls off before I drive 1000 miles!!!

I was looking for a before and after within Nissan Motor company or the Japanese auto industry as a whole. If Nissan never used cadmium then it seems illogical that they would start in 1969. The S30 is just another car of course. The same fasteners were certainly used across the model range. If they used cadmium in 1965 on a different model, you'd expect them to keep using it on the S30 unless they had a reason to change. When was the shift? And, on your final point there - still no evidence that supports your statement, besides a Nissan document that identifies an alternative plating material. If you had a document that showed cadmium from earlier years next to your document that shows zinc, that would have some weight. Evidence that Nissan removed the word cadmium from their documents would be telling. So far, there have been many many words written on sparse evidence. 1970 was so long ago. All of that paper and ink. How did they get anything done?

Taking sides doesn't lead to learning. Independent thought does. HS30-H might be trying to influence 26th-Z, or just expressing surprise. After roaming the electronic wasteland I finally decided to see what one of the AI models would generate, even though I really hate how you can't do a simple Google search today without AI butting in with an opinion. Supposedly they collect all of the available data on the WWW and distill it down to its essence. BS of course since processed garbage is still garbage. But it did come up with an interesting comment. In this case the absence of evidence is actually telling. The great AI large language scavenger found nothing. But, of course, I also found evidence of a ban, showing the weakness of today's "AI". In 2007, last link below. https://www.google.com/search?q=when+was+cadmium+banned+in+japan JAMA document with an interesting note. https://www.jama.org/wp-content/uploads/2014/06/The-Motor-Industry-of-Japan-2014.pdf

I'm not about to wade into this discussion except to say that I think there's a lot to be said for the quoted comments. First, I like, and get in this context, the Shakespeare reference. Ouch! I'm betting it was a weak moment for 26th and he'll be back onside soon. But more importantly, if there's a community on the internet more dedicated to knowing everything there is to know about Datsun Z Cars, I haven't found it. This is it. Sometimes it takes a long, rancorous discussion to get to the answer, but down the road it's only the answer that will matter. Good for you guys for caring enough about this stuff to challenge each other to get to the right answers. Not everyone will care about whether it was cadmium chromate or zinc chromate, but a few will, and we stand a better chance of determining the answer today than we ever will in the future. Cheers to you guys for your dedication to the cause!

Apparently they made a special 240Z for Carl Beck with Cadmium-plated parts. ;-) To be serious - just for a moment - your question is very wide in scope. Nissan have been active since the 1930s in numerous sectors of the automotive field, including war materiel, so it seems very likely that they and/or one of their numerous suppliers will have used Cadmium plating at some point. But we are only looking at the S30-series Z range here, so - as far as I am aware from looking at period documentation - no Cadmium was used when 'our' cars were made. Can't speak for anyone else, but I'm not. I understand the difference. Not to mention JIS, JSAE and NES. Japanese industry standards are somewhat germane to the discussion, I'd say. Et tu, Brute? OF COURSE it matters. Getting your hose clamps oriented to the same way they did when the car left the production line is a matter of life and death for some of us. And those rivets don't count themselves you know. If WE don't do it, who will?

The point was that cadmium is still being used to plate parts for old cars. Zeddsaver is just an example.

I am only talking about the element cadmium, 48 on the periodic chart, and its use in plating metal parts for corrosion protection. Carl Beck suggested that early 240Z parts were plated with cadmium, HS30-H disagrees. Carl Beck says that he had some parts analyzed scientifically, at Honeywell. It's been a long discussion, not one that can be absorbed fully without reading most of the last three to four pages of posts. https://www.anoplate.com/news-and-events/what-is-cadmium-plating/ https://periodic-table.rsc.org/element/48/cadmium

Please, please be most careful when suggesting ANYTHING from zeddsaver. I, and a number of folks I spoke with over the years , had problems, some big/significant.

It's been a dozen or so years since new, but whatever glue I used on the rear hatch weatherstrip of my 240 is failing. Looks like I didn't miss any areas, but the rubber is just coming a adrift. The original stuff on my '78 Mercedes and day-to-day 2006 GMC are still looking good. Any recommendations as to which adhesives to use, and which to avoid? Thanks, as always

Thanks for sharing! I don't watch much TV, so when Diane told me there was a Nissan ad with what looked like a yellow version of my 240, I had to check. Cool ad, although there will be those among us who find the rubber-burning, wheel-spinning parts to be "deeply offensive," to which I say, "suck it up baby sisters."

Quite the discussion. You all seem to be describing an element metal by its color. Cadmium is silver. It's the chromate additive that makes the color and you can't tell the difference between the cadmium chromate and the zinc chromate. There are ASTM and SAE specifications for plating in these materials. Yes, you can have cadmium chromate plating but how does this all matter? So, I wrote a brief forward and printed five copies of the original 2005 script. They are about 35-40 single sided pages, color pictures, spiral bound with a cover page. It cost me about $15 each to make this nice. I really need to keep one, two are spoken for right now so I have two and I can always print more. Let me know.

Did Nissan ever use cadmium plating? Was it in use and they switched or did they start with zinc?

Vague? The Nissan literature - I've put it in front of you many times on this thread - reads ' 亜鉛メッキ ' (Aen Mekki). That translates fairly literally as 'Zinc plating', but many people will take that a step further and translate it as 'Galvanizing' (English spelling 'Galvanising', with an s). Black Zinc is also on the list. So we have an old-Japanese Kanji word for an element ( 亜鉛 ) sitting next to a modern Japanese version of an English technical process term ( メッキ ) written out in phonetic Japanese, Katakana. There's nuance involved which may well sail over heads who are not used to Japanese-English-Japanese translation, but the bottom line is that we are talking about a protective coating of Zinc, applied via electroplating ('Mekki'). You might be interested to hear that the original usage of the term 'Mekki' in Japan was in connection with Gilding. Yes, it's not strictly the true Galvanizing process (more suited to water tanks and shed roofs) but there's the nuance... People who insist on 100% literal terminology might be well advised to steer away from ideogram-based languages and their writing systems, for there be dragons. You might notice - although it's hard to tell given your "therein lies the problem" - that no Cadmium is mentioned. Yes, noted. Although I have a hunch that we might be going to hear a little more about that soon. Stay tuned.

A bot seemed to find its way into the site. I squashed the bot with Bender.

And therein lies the problem Galvanizing and Zinc plating are two totally different processes, the only thing they have in common is Zinc. If the Japanese specification is this vague then there will always be some confusion to what type of coating was used on the parts. Coming back to the Vintage Z restoration program of 1996-98 in the USA; Nissan Motor Corporation USA was very specific that Cad plating be used and listed it repeatedly in their "Quality Control Checklist". They also listed suspension parts be painted semi-gloss black not powder coated. There is no confusion here, it's all in black and white on the document.

So far it appears that cadmium was NOT banned in Japan in 1970. Therefore it is possible that cadmium plated hardware was available in the automotive industry in 1970 and early 1971. Carl Back has evidence apparently obtained from a very reputable high level technology company, Honeywell, that cadmium was present on the hardware he had tested from 240Z's. It's not clear how much. Maybe a plating bath was contaminated and there was just a trace. Mistakes happen, and sometimes deception. There are easily imagined scenarios where cadmium plated hardware could make it on to a 240Z production line, especially since cadmium was not banned and was still used in "more than 1,000 Japanese plants" in early 1971 . At this point the argument is between what Nissan's documents say, and what Carl Beck observed, and what general public documentation from the time period describes. That's the whole thing in a single sentence. All that I've done is add a little bit of clarity. Forum members can draw their own conclusions. The main point, Carl Beck's public service announcement, in a way, might actually be for people working with early 240Z hardware to assume that it might contain cadmium and to take appropriate precautions. Especially since the aftermarket appears to be offering cadmium plated hardware. Maybe Carl got some aftermarket bolts? Who knows. https://www.zeddsaver.com/pages/about-us https://www.nemetalworks.com/cadmium-plating-services

Let's take a look at the random example of a bolt from the front suspension. It's one of the hex bolts that holds the balljoint onto the transverse link. Part number from the 1970 Nissan C-187 Parts Catalog for the S30 and PS30 models is: 81-30820-65 BOLT WITH WASHER. Nissan Engineering Standard (NES) tables, the '81' prefix identifies it as a Hex bolt and the '65' suffix - when you look it up on the above table - shows us that it is Galvanized/Zinc Plated.
