I know the info is in here some place but computers aren't my friend. I've been told that some late 60's 3/4 ton with auto. center sections with fit my 50 3600. can anyone tell me which ones.
All of the 3/4 and 1 ton diff set ups are pretty much interchangeable. I can't remember completely, but it seems like the 67-72 gears needed something out of the pumpkin to work in the older housings.
I was looking into doing a swap a while back, but then decided to leave it as-is because a) it was too much of a pain to do it and b) I kind of like being able to change the rotation of the Earth in first gear.
