As for what trans, I'd think anything that would bolt up and that isn't computer-controlled.

 

What about a 5 speed from a late 80's early 90's f-150 manual floor shift and it's an inline 6 just don't remember the year exactly.

 

The Mazda and ZF 5 speeds require a hydraulic clutch.

The 4 speed OD trans would bolt up, might be a true bolt in.

Another 3 speed--millions served--could be found.

Pics, info here on then 4 & 5 speeds--the 4 speed ODs are first up:
