4x4 tranny question
 

I have a 1971 K20 4x4 with a TH350 and NP205. Are the 4x4 trannys short shaft? and 2wd long shaft?

Re: 4x4 tranny question
 

yes sorta something like that you would have to swap out shafts they are different
from 2wd to 4wd

Re: 4x4 tranny question
 

The shaft and tail housing are different,To swap out the shaft you almost gotta rebuilt it to do so.

I think short and long are used with 2wd TH350s. The 4wds do not have a shaft since they have an adapter for the transfer case.

The 4x4 has no tail housing, the trany bolts directly to the 4x4 adapter. It does use a shaft but it's specific to the 4x4's. It's much shorter.
