My son snapped the pinnion on my 80 bj40 with a 3b and 4spd , the driveline jammed and split the TC. What I have here to fix it is a 78 4spd with TC (2F eng) and a 63 TC, After searching I think that I can swap the 4spd & TC if I change out the Trans input shaft, or switch out the 78 TC onto the 80 trans or use the 63 3spd transfer case and switch out the gears.
Am I Correct with these thoughts and which is the easiest and best way ? Is the 63 Case weaker IRC the early ones were ok.
I am assuming that the 80bj40 should have 4.11s and will be the same fine spine as the rearend I have out of a 78 FJ55.
He claims that he was just pulling ino a gas station, I would be willing to bet he was trying to spin the 35s with a turbo'd
3B !!!!!
Thanks Myrle
