  1. 1971 HLS30-14938 "Lily" build

    I did this replacement earlier in the year. Very pleased with the end result as there is now zero slop (more like, 'click') in the front and rear joints. A couple of tips: When you reassemble, it helps to chill the needle cups before inserting them into the yoke. I used a spray can of 'Part Freeze'. Doesn't hurt to also warm up the yoke ears , too. I used a heat gun. When you're pressing the cups home in their bores, be careful not to let one of the cups go too far so that it travels past the inside face of the yoke. When this happens, the cup behaves like it has a slight draft angle and it won't back up into the bore. Maybe it gets cocked a bit sideways, too. Whatever. Bottom line is that the cups will go one way (in), but they won't go the other way (out). I learned this the hard way and ended up having to cut a brand-new spider in half in order to extract the cup from the yoke. After that, it was back to the cycle shop to buy another one. You may need to dress a bit of metal 'flash' off certain edges of the spider casting (forging?) before you'll be able to get the second yoke in place. You'll know which edges need to be shaved when you try to assemble the parts. You won't need to remove much more than ~ 1/64", but without doing this there may not be enough clearance to get the second yoke ear to fit over the ends of the spider. What with chilling, heating, and pressing, you're probably going to make a bit of a mess when you're doing the re-assembly, so save any painting until everything's back together.
  2. Recommended car cover

    This is a well-travelled topic that's been discussed for the past 40 years. Perfectly-tailored fit is a nice-to-have, but not a need-to-have. What you need is a combination of outer and inner materials that won't hurt your paint. Trapped moisture can kill an expensive paint job. My suggestion: Go to a Ferrari owners website and have a look at what's considered to be the accepted standard. What you're looking for is experience-based advice coming from people who won't tolerate bad surprises.
  3. I'm using a very compact little relay box that I pulled out of a 2000-ish Mitsubishi SUV at one of the local boneyards. I had to do a bit of internal re-wiring, but ended up with a configuration that holds 6 relays. I plan to mount it up towards the rad bulkhead, in front of the voltage regulator. It's waterproof and dustproof, with a snap-off inspection cover.
  4. changing camber using the strut insulator

    Another example of how 'creative destruction' can reveal the inner workings of an assembly that usually just gets taken for granted. Does the inner cup make metal-to-metal contact with either the top cap or the spring perch, or does it 'float' 100% within the rubber? If it floats 100% (and I'm guessing that it does), the thickness of the rubber that separates the top of the inner cup from the underside of the top cap is going to be important. Do you have any sense, or way of measuring, what that thickness was/is for the original configuration?
  5. changing camber using the strut insulator

    Chris: Why not contact Steve at 240Z Rubber Parts? He's been casting soft and hard 'rubber' parts for a couple of years now and should be able to offer some useful tips on materials and processes. Use the 'Contact Us' link in his website.
  6. Are the seat strap clips available anywhere?

    Contact zKars. I'll bet he's got a drawer-full of these in his storage room. If you're in a hurry, though, there's no reason why you can bend your own. However, you'll need to temper the steel afterwards, or else they'll just bend and pull out after you've sat on the seat a few times. Heat the formed clip cherry red with a propane torch, then dunk it in cold water. Not terribly scientific, but close enough.
  7. Nice write-up, zKars. A few additional questions for you: For an SU application, what is it that creates the end-of-travel (WOT) stop for the system? Does the 'commercially-available arm' hit a stop? Does the pedal hit its stop? Or do the throttle plates hit their stops? How does this affect the travel distance of the pedal, from rest position (idle) to the point where the system hits its stop? Where did you source the M8 ball-sockets and the 'commercially-available arm'?
  8. Are the seat strap clips available anywhere?

    Pretty sure he means these...
  9. Caswell Plating

    Non-chemists messing with chemistry = alchemy As an engineer, I hate 'hit-and-miss' when I know that science offers a better solution. Unfortunately, I'm not a chemical engineer
  10. Caswell Plating

    Hah! That depends on your definition of 'finished'. I completed everything I wanted to do, with the exception of the my hood prop rod. I bought a replacement prop rod from Zkars and it arrived after I'd put the chemicals away and after I'd given Grannyknot back his controllable power supply (which I suspect he figured he'd never see again -- Chris a remarkably generous, patient, and polite guy). Some observations from my electroplating experience: To anyone just getting started on a plating project, I recommend you ignore all the 'budget' plating articles you'll find on the internet. I spent so much time and money experimenting with these DIY, low-buck recommendations (epsom salts, corn syrup, vinegar, etc.) that I would have been better off spending $500 to get a commercial outfit to do the work for me. If you really want to do it yourself, just hold your nose and buy the (premium-priced) Caswell chemicals. They work pretty well, for the most part. Even with the Caswell chemicals, there's a lot of trial and error involved. To get a good end result, everything needs to be right and there's zero tolerance for parts that haven't been properly cleaned and prepped. I hindsight, I don't think electroplating scales down well to the 'hobbyist' level. Or to put it another way, I suspect that, 'The bigger the vat and the heftier the power supply, the better the result'. I had mixed results trying to do multiple small pieces at the same time. This just seems to increase the chances for error. The 'Mount Everest' for my S30 plating project was getting a good result for the two-piece engine inspection light housing. With it hollow configuration and welded-on mounting bracket, it's hard to get complete, even plating coverage over the outer surfaces. It took me two tries to get a result that I was (sort of) happy with. Plating longer pieces (like the hood prop rod or the rear engine coolant transfer tube) will force you to buy a double-quantity of the Ca$well chemicals in order to get a bath volume big enough to plate these pieces in one shot. I don't think I'd try this job again without a controllable-voltage/current power supply (add $100 - $150 to your budget). I tried using a fixed-voltage power supply to start (I used a daisy-chain of automotive 12V bulbs to control the current), but it was a PIA and the results weren't very good either. I remain a little concerned about the durability of the yellow chromate finish on my parts. On some pieces, it would wipe right off. Some people suggest that the parts have to be baked in an oven after plating. Maybe this 'locks down' the chromate? I'm thinking about trying a two-stage powder coat as an alternative to yellow zinc plating. There are some pretty interesting 'glaze' top coats available these days.
  11. Paint or re zinc fuel lines

    I used flexible sanding pads (foam-backed sandpaper, about 400-grit) to remove the heavy tarnish, followed by fine-grade 3M sanding cloth to bring up the shine. After that, I dipped a piece of cloth (lint-free) in satin-finish clear enamel paint and used this to hand-apply 2 cover coats along the length of the line. This work was done over a year ago and the lines still look great, with no signs of corrosion. The OE steel lines shine up very nicely and don't really need a color coat. Depends on your aesthetic preferences. Applying the clear coat with a wetted cloth makes this part of the job really simple and mess-free. If I showed you one of the finished pieces, you wouldn't be able to tell that it wasn't sprayed on. Use a dust mask when you do the sanding. The sanding residue that comes off the lines is pretty evil and seems to fill the air while you're doing the work.
  12. Caswell Plating

    FWIW, I found that I had to keep 'doping' my bath with the Caswell's 'brightener' liquid to keep my zinc plating coming out shiny. It worked really well.
  13. Choke Cable Grommet Installation 1972 240z

    Another option (which may or may not appeal): Rubber/neoprene grommets respond really well to 'super glue' (aka KrazyGlue'). Just slice the grommet across half its width, position over the cables, apply a drop of glue to the cut surface, carefully line up the edges, and press together for 30 seconds. Job done. If you do it carefully, the joint will be pretty much invisible... and more than strong enough to withstand the distortion of the grommet when you push it into place in the hole in the firewall. If you need convincing, buy a generic grommet from the hardware store and try it out.
  14. Rear hatch weatherstrip

    Just did this job myself. To confirm for you, the lip faces away from the hatch opening (i.e. faces to the front of the car for the section that goes over the top of the hatch). Before you get started with the adhesive, use a paint-friendly cleaning liquid to clean both the pinch strip surface and the surface where the lip will seat. Use the same cleaner to clean the inside groove of the weatherstrip, as well as the bottom surface of the lip. Apply a light coating of weatherstrip adhesive to the inboard edge of the pinch strip. Also apply a thin smear of adhesive to the underside of the weatherstrip lip. Forget about applying adhesive "to both surfaces" (overkill). When installing the weatherstrip, start from the centre of the top of the opening and work outward to one side and then down. Then go back and do the other side. The weatherstrip will stick pretty firmly right from the get go, so go slowly and avoid creating wrinkles. Be extra careful around the upper corners of the opening. The pinch strip isn't very tall and it's easy to miss the actual contour of the corner when you're pushing the weatherstrip into place. Pushing a length of clear-vinyl tubing (1/2" diameter?) down into the groove so that it presses down on the lip will help to seat the weatherstrip properly (especially around those two corners). If you don't remove the hatch from the car, it will be a bear of a job (maybe impossible?) to install the weatherstrip properly over the top of the hatch opening. Probably a good idea to apply painter's cling-film over the roof and rear quarter panels around the opening before you get started with the adhesive.
  15. Mustache bar bushings

    Well, not quite NLA... but close ($145!) http://www.ebay.com/itm/Datsun-240z-280z-Differential-Bar-Stopper-Mount-Bushings-Upper-Lower-NOS-/282099223385?hash=item41ae6c8b59:g:w4oAAOSwY45USAog&vxp=mtr
