Hello, I`ve got a question for the connoseurs! I have a '75 BJ40 which I am rebuilding. I also have a '80 HJ45 with a transmission & transfer case in excellent shape. Since the BJ40 has a B engine & the other one has an H engine, I know transmissions are not interchangeble, but the question remains - are the transfer cases interchangeable? I want to do a swap, since the truck I want to use more often is my BJ. Both trucks are running and it would be a major hassle to pull apart both transfers just to find they are not interchangeable. Thanks for your responses, any leads are more than welcome. BJ40man in Honduras, C.A.
