Zf5 to zf6

[Roger.westgate]

Looking for some answers on this. Have a 79 f350 6 inch lift with a three inch body lift to fit a zf5 bolted to a 460 out of a 71 lincoln under it. Currently has a np 205 t case. Had a thought about swapping with a zf6. Any one familiar with these transmissions that could help as far as bolt patterns, splines, crossmembers and what i can run for a t case (if i dont get a divorced) i would like to keep my 205 or simmilar so i can keep the drive shafts simple. Any help is much appreciated

I don't know the exact specs but the ZF6 has a larger input shaft, it would need a different clutch disk and pilot bearing. And I'm not sure the is a ZF6 out there with a 385 bolt pattern.
