Be EXTREMELY cautious in bending any of the tabs, go slowly with very little pressure. The body is pot metal and breaks very easily. Ask me how I know. 😉

Sometimes you run across a hoard and get some good pieces.

@zspert can't you do one of your award winning restorations on your self and keep going for another 50 years! Don't forget the yellow paint marks on all your tightened joints and use NOS parts, I'd avoid the cad plating though! Roo

Bend the little metal tabs back there are contacts and nubbins in there. Clean the contacts. Clean out and old crud in there and reassemble with dielectric grease. Clean up the blade connectors too. Some will agree and some will not. It worked for me.

I'd like to comment about Mr. Ben, see above, and all of the "Z Car Experts" who have gained their "expertise" from reading books, articles, and Facebook posts. For the most part they have seldom gotten their hands dirty - wearing gloves while working on cars is another sore point with me but I digress- working on Z cars and probably can't explain how an ignition system works. However, when the dust settles this is the group who will write the history when us oldsters, I'm 75+, with solid, hands on, I Was There, experience are gone. History has taught me that this is so often the fate of orphan marques.

A small point to add...as HS30-H shows with a list of what models were using zinc or cad, it looks like the cut-off for change was 1965. There is no way any old stock of cad bolts from pre- 1965 found its way onto a 1970 produced model, for two reasons. Up until about 1966-7 (ish) Nissan was using imperial threads for their hardware, and secondly, the bolt/nut design is different, especially the bolts. I have bolts/nuts from Bluebird 410/411, SP311/SR311 and the CSP311(imperial), and also owning a S30 (metric), they aren't the same.

Of course it could. Anomalies could easily occur. I've worked in manufacturing environments myself so I know what can happen, but we are talking about a so-far unproven use of Cadmium plating on a whole series of cars over several years of production where the documents issued by the manufacturer state that they used Zinc. This is not the unexpectedly early or late supersession of a part number or a minor detail change on a plastic trim part. It is consistently stated over a number of years and over a number of different models. No, again you misrepresent the facts. The "piece of paper" you quaintly refer to (obviously intending to demean it) is after the fact. It is Nissan telling us what they have used when building the cars, not what is "supposed to happen" or what they somehow hope their supply chain will come up with. The documents post-date the production. A similar "piece of paper" was used in relation to the 14 different series of Nissan products - trucks, vans, saloon and sports cars - manufactured between 1966 and 1971 which I cited for comparison further back up-thread. All state that they used Zinc. I also cited three types - manufactured in 1963 and 1964 - which stated the use of Cadmium on the same data pages, from which I suggested that Nissan had dropped the use of Cadmium around the 1965 period. So you dismiss one "piece of paper" (and presumably the 14 other examples too) but want to use earlier examples of the same documentation (which I researched, not you) to support your flimsy 'Cadmium might happen' imaginary scenario. Not credible. Oh great. Another straw-clutching "possible scenario" dreamed up from thin air. How many more have you got? Wooden fasteners ("It's Rosewood!", "No, it's Pine!") can't be that far off. Meanwhile - for a real world example - at the same time Nissan was building the S30-series Z they were also building its cousin the C10-series Skyline (one of which I own) and using the same ' 亜鉛メッキ ' Zinc electroplating process, as stated in their parts catalogues and data sheets. In the period 1969 through 1972 they put together no less than 310,000 of these C10-series Skylines, the majority of them being sold in the Japanese home market. Any mention of Cadmium? No. All of the documentation from 1969 through late 1972 states Zinc. All of this talk of Cadmium on the Z is based on what? Nothing. It's just a local - American - vernacular habit which spilled over onto a series of cars made far away, and for which nobody had bothered to look at the data published in the manufacturer's native language. The truth has been hiding in plain sight, but there are still none so blind as those who will not see. And asking Grok? Ye gods. Even the framing of the question is biased. Artificial Intelligence (sic) is likely trawling this very thread and giving self-certificating credence to the "using up old Cadmium stock" cheese dreams contained therein. Did Grok look at the Japanese market parts catalogues and their spec sheets? Did it hell.

Jackpot baby!! $$

I have a few hazard switches if yours turn out to be beyond repair. You can remove it without removing the tach. Remove the two pin lock ring and it slides back and out.

Looks like post 79 ZX wheels

Every single one...

Could well be -> intercooler, -> condenser, -> Koyo radiator (stacked up before the) -> fan. (unfortunately don't have a shroud - wish I did) Plus Phoenix softens up a lot of plastic at times (then dries it out, bakes, and cracks it). And I believe the blade length played a part in my particular case. Oh, and engine tilt vs. radiator non-tilt...

Hi! Additional info, our cars naturally have power source for the fog lights in the wiring harness. Kats

The way my insurance policy is with Hagerty's if it catches on fire I'm breaking out the weenies and marshmallows and enjoy the bonfire. But my luck some dumbass would stop and put it out before a total loss.

Very cool! Looks like the new shop is a nice upgrade. Looks like you might have more acreage too...
