I posted a picture yesterday of my flywheel that had been machined (the bolts go beyond the face of the flywheel) and now I think that's going to be a problem. Upon installation as you can see the clutch arm doesn't have enough play to fully disengage the clutch, it hits the tranny housing. You can also see I had to fully thread the cable to get it even remotly tight, so I knew I had a problem here.

Question is, what can I do? When I installed the pressure plate as I tightened the bolts the release fingers kept going in as the plate seated down, I'm guessing because the face the edge of the pressure plate mounts against has been turned down too much??? Bummed, now I got to pull it all out again, but do I need a new flywheel?

Thanks for any suggestions!

I thought I answered this when it first appeared. The flywheel's been cut too deep, whether or not they did it right (and, despite the earlier responses, there's no visible information that it's cut wrong). Even if they cut the mounting surface so the disc won't hit the heads of the bolts, the pressure plate mounting surface is too low. The release arm pivot ball can't possibly be shimmed far enough to correct the geometry. There are only enough threads for 2 flat washers, and it looks like you might need 4 or 5. You persist in using this setup and you're gonna be repairing the clutch cable tube through the body, sooner rather than later. New flywheel time .....................

You did answer it Cap, But it was after I had already installed the tranny in the car, so I missed your post. Many have said to shim the pivot, but I agree it looks like I'll need too much.

I'll pull the flywheel and measure today just to see how far off it is, but it sure looks like I'll be needing a new one.

Thanks for all the help, this site's great!
