  1. The clutch diameter and the discs remained the same for all base with a larger diameter for the 2+2 and turbo cars. What changed was the thickness of the pressure plates over the years and that's why the collar changed many times. A lot of clutch kits now include the collar since it's hard to know what parts have been swapped over the years. It's best to measure the height of your collar and then buy a clutch kit that matches that collar height.
  2. You match the sleeve to the pressure plate. I think I have the chart somewhere. If I find it, I'll upload it. EDIT: Here is a link to the previous discussion with the chart.
  3. I want to say his first name is Greg, but that's relying on 25+ year old memory. He was a bit grumpy and rough, but at the time, I was able to buy a 99% rust-free rolling shell for $650. It's now restored and is a beautiful car.
  4. Hmmm, I have no idea these days, but that *might* be the same guy I bought a '72 rolling shell from back in about 1995. His name was Clark and he sold Z's and Z parts from somewhere in AZ. Even back then, he was slow to respond and when I got the car, he had swapped some body parts with the car next to it. I bought it sight unseen and had it shipped to Michigan. He sent pics of a bunch of different Z's when I told him what I was looking for. In the background, there were a bunch of other Z cars. I picked a car based on pics and his description and when the car arrived, the front fenders
  5. That's what I raced on for years. They are really small for street use, but were the only good performance tire in a 14"
  6. Be careful, I've had several old tires explode during storage. The belts broke and the tires exploded. One was on a car and the other was stacked.
  7. Nice find! I made my own for both of my Z's with Optima batteries which are about the same height as your battery. I think I have about $20 in steel for both and for the most part, I only used basic tools, though I did have to put a few welds on them. I even posted a dimensioned drawing on here 15 years or so ago.
  8. In the early 2000's, Ford SVT bought a used Dodge Viper as a competitive vehicle for our upcoming Ford GT. It was low mileage and looked good, but it ran like crap once we got it on the track. We found that a PO had used anti seize on the plugs. Once everything was cleaned off, it ran great. At the time, nearly all of us had been using it on our personal car plugs, but I never have since. I have enough old car gremlins to chase and I don't need another one that is self induced. 🙂
  9. Be careful. Anti seize has been known to cause misfires due to disturbing the ground path of the plugs.
  10. Wow, those look terrible. Did they forget to use spring steel?
  11. I think the packed mud is a clue that the car spent time on a dirt road. The mud likely packed between the coils as well as below them and caused coil bind when subjected to full jounce travel over the rough dirt road. The owner likely overloaded the car often with kids and stuff in the trunk making the situation worse. Once a coil broke, the car would sit lower and when not repaired, the next weakest spot failed from being subjected to unusual forces from the spring position. The rust might be minor, but it did likely factor in a bit.
  12. I can't believe Fidanza supplied dowels that are clearly the wrong ones for their flywheel. I've never bought a Fidanza flywheel, so I can only assume they grabbed dowels from the wrong bin when they packaged it. Glad shortening them worked.
  13. Yeah, that's your problem. They are bottomed out in the flywheel, right? Do the pressure plate holes match the smaller diameter of the dowels, or are they loose?
  14. Do you have calipers? If so, measure the OE pin diameter and the new pin diameter and see if they match. When you say they are stepped, does the step sit flush with the flywheel? If not, the PP will sit on the step and never seat against the flywheel.
  15. The tolerance between the dowel and the pressure plate is off a bit. Check for burrs on the dowels and PP holes. The dowels should be snug but should not impede the PP from clamping down tight against the flywheel. If you must, gently file the holes just enough so they slide over the dowel pins.
