The early 518s are from my understanding just a couple wires and a switch. Youll still need to source a gm Transfercase and probably Fab a crossmember or mod currect. I plan on a 518 behind the 400 in my wifes 70s Powerwagon. She wont wheel it like I plan to mine.
Good luck
yep if you can find an early 518 they had 3 wires 1 hot and 2 grounds.
and if my memory serves me correctly they even had a 518 that had no lock up, so any 727 converter would work but they would be harder to find
