Clutch Issues
Just a comment from my desk. The entire clutch industry has suffered from incorrect installations of the classic GM RWD release bearing to fork ever since the system was introduced. For those of you that have never installed a GM RWD clutch (pre 1996) you can put the bearing on the fork about 4 different ways, only one of them will work and release the clutch, doesn't matter what brand. The complaint is always, no release. We put a bulletin in the sets to explain the correct method. Welding the lever adjusting nut has been around since these clutches made it to the aftermarket. It is there to lock the lever height and prevent individuals from "tweaking" the adjustment. Another general comment, you can only measure finger tip height when the clutch and disc have been bolted in place and exercised to settle the fingers into position. We have customers try to do it on the parts store counter all the time, it can not be done.
FWIW I quit buying any GM product back in 1986 because the paint came off like it was peeling. I think GM has changed their painting method since then.
