Hello, I have a NP 208 Transfer case that came out of a 1985 Ford F250 4x4 with 4 spd and 460 engine. I have been seeing ads for sale on NP208'S in Blazers. Is this the same transfer case. Mine is possibly a NP208F. This case has six bolts to hook it to the tail shaft and is a locked yoke. Any info appreciated or a link or two for reading would be just great.
Thanks in advance.

 

This should answer your questions:

the thing you have to worry about is the spline count. is your transmission spline going to slide into the transfercase

 

Yeah, as the link I posted above states, the Ford NP208 has a 31 spline input while the GM has a 27 spline input when behind a TH350 or TH700R4 // 32 spline when behind a TH400 or SM465. The clocking of the transfer case is also different.
