zf6 swap complete....almost

just got done swapping in a 99 zf6 in to my 96 f350. it was an auto. the only problem i have is i cant get the clutch to release completely. cant put it in gear with the motor running, wont shift with the clutch but i can "float" the gears. i have the stock obs pedals and master cylinder with a zf6 slave cylinder.6 speed flywheel, clutch, and pressure plate. was there supposed to be a spacer behind the flywheel like the tc had? any ideas? /ubbthreads/images/graemlins/confused.gif its been done for 2 days and cant get this last little bit worked out. ive been so frustrated ive thought about selling it lol. any help is greatly appreciated. jesse :
