I have a 79 F-250 4x4 that I have torn down to the frame. It currently has a C6 mated to NP205. I would like to swap in a newer, manual heavy duty tranny with an OD. Has anyone tried bolting a ZF to a 205? Also, what is the case length of a ZF from rear to front of bellhousing? Thanks for the info.

[updated:LAST EDITED ON 12-Nov-01 AT 10:31 AM (EST)]I'll tell you what I have learned from doing a 5 speed to 4 speed swap recently.

I believe the ZF and the M5OD have the same output configuration. I'm assuming this because they were used interchangably in late model F250's. My swap consisted of removing a bad M5OD from an '89 F250 and putting in a NP435 from a late 70's 4x4 truck (78 or 79, not sure which). My '89 has a BW1345 transfer case, this bolted up to the NP435 perfectly.
So, here is my thereoy: Most Ford (fullsize) 4x4 trucks used the same output shaft and bolt pattern configuration (unless it is a divorced transfer case). So, my guess is yes, the ZF will hook up to the NP205. I also know that the M5OD is about 3 inches longer then the NP435, so (I'm assuming again), the ZF would be about the same (around 29 to 30 inches).

If I am wrong, someone, anyone, please feel to correct me.

Hey man, I was wondering if your swap worked. I am currently in dire need of a C6-NP205 adapter. If you need an NP435 adapter, I have one. I will swap you straight out, or even pay you for yours. If you are interested shoot me an email.

it will work but .... you have to do some trimming on the back of the zf trans to clear the rod for the that shifts the t-case
