Ok Look at the pic, and tell me if I have the right length clutch rod for a 71 Cuda 440 4-speed? It's 7 1/2in. over all, and 4 1/4in. of the shaft is threaded. The problem is the clutch wont even start to grab until the pedal is almost all the way let out. I've maxed out the adjustment on the shaft, and it got a little better but not like it should be. It's like I need more threads on the shaft to adjust the clutch. The clutch is a center force dual friction very little miles on.
