ive got an 89 150 4x4 with the 1356 b/w t-case there are large chunks of metal floatin around but it still works was wondering if a np 205 from a 79 or so bronco would bolt up to my aod i know ill have to change the drive shaft flanges and maybe some other things but i can get this case for around a 100 would this be worth the swap or will it even work

 

As far as I know all fords use the same input gear for the transfer. Check Advanced Adapters for better details and the correct mounting flange.
