Hi i have a 1988 Chevy 2500(6 lug) with a brand new 5.7 350 4 bolt main with a th400 trans, I think i have the np241 transfer case. I was looking into the swap for overdrive because i drive a lot for work. Was wondering if it will bolt right up or do i have to make some modifications if so what has to be modified. Thank you for your time.
