Well have no way to know if the tranny is the orginal one. It is all spline though. I have measured the shaft in reference to the pilot bearing all looks good to me. I have also looked at the pilot when I removed the tranny and the front face interance of the pilot looks clean and rounded... not scared ...so the shoulder is not hitting it.

New news: Sachs says the clutch kit is the right one per their books for the Nova and the amount of travel need on the diaphram to dis-engauge is .455". I know that my car does not deliver that much throw (maybe .350"). I have asked them to look into other pressure plates that would require less throw also... but waiting.
Either my cars zbar/padal hardware has some mismatch of parts or Sachs books are wrong.
If someone could measure their (Nova)fork rod travel I could narrow my search. Mine is about 3/4".
I am posting on a couple of Nova sites also... maybe someone here has a 62-67 Nova?

Thanks for the input, Clyde
