I've had a similar problem. I'm not sure if this applies or not but twice I have installed a new clutch disk and later found out the disk was too large in diameter. The disk would hang up on the flywheel where the outer edge of the clutch disk meets the recess for mating surface of the flywheel. Does that make sense? Some flywheels have a recessed surface for the disk (1/4" or so?). Had to pull the T-5 out of the S-15 again and check it. Should have fit the disk first and would have seen the problem.
I don't know if this is a clutch disk remanufacturing flaw or what. But now I check it first to save a lot of headaches.
We live, we learn.
