I have to admit that I screwed up while preparing the 5 speed for my car. I
didn't catch it until I assembled the tranny to the engine and what I
discovered was that I used a 4 speed throwout bearing sleeve on a 5 speed
tranny. The sleeves are different and one won't work with the other.
Fortunately I did catch it before I installed the motor in the car but it
woulda been horrible.
