I just did a 4 speed conversion for a 70' GTO and used pedals and linkage parts from our host. After finishing, I couldn't get the clutch play adjusted right for nothing. If I got a little play with the peddle up, it was out of adjustment at the bottom, and visa versa. I finally pulled the transmission back out and found the clutch fork was the incorrect length from the clutch pushrod to the pivot point where the clutch ball sits. That's comparing it to several original clutch forks I had laying around. Also, the clutch Z-bar had a lot of slop at it's pivot points and therefore was flexing. I put stock components back in, and reinstalled the transmission AGAIN, and it was good to go.
