I have a '78 f150 (they are awesome) it has the 4-speed but to improve gas mileage I wanted to put a 5-speed in from a '85? or '88 but I don't know if the bolt pattern from the bell housing is the same or what i would have to do? Anybody know anything?

 

Depends on what engine it has.

 

It can be done, but we need to know more. What engine does the '78 have? Is it 2wd or 4x4?
