Hi guys, I'm new to gear swapping and had a question that I haven really found the answer to after searching. So, I have a tapered D44 with 5.38 gears under my Jeep now and I just picked up a 1971 flanged D44 with 3.73 gears. I was wondering if it was possible to swap gear sets between the housings. I want to put the flanged rear under my Jeep with the 5.38s and I have a friend who said he would buy the tapered one if I could put the 3.73s in it, so win/win, but aside from having someone proprely set up the gears, what else would I need to do? Thank you!
