Transfer case NP208 to BW
I have a 84 F250 4x4 with the NP435/NP208 setup. After 300,000 miles the old tranny is wore out, I got another NP435 with the BW(forgot witch one but all manual shift)transfer case. Will I have anyproblems with drive shafts if I put in the BW transfer case in place of the NP208? And if I do have to swap, are the input shafts the same from BW to NP transfer cases?

Measure the length of the transfer cases. If they are different lengths (and they probably are) you will need to appropriately lengthen/shorten your driveshafts.
The broncos use a fixed output yoke and the trucks use a slip yoke.
