I do think that the "Camper Special" trucks back in late 60/early 70's are candidates as well as some panel trucks, and maybe even some 1 ton or C30 model Chevy trucks. Also some Jeeps may have used Eaton gear sets. Checking in on a jeep forum may have rewards. Good luck

My 69 1 ton dually 350 4 speed shows on the glove box sticker that it has 4.11 gears and posi. Would this rear be the same as my 52 1 ton DRW? I was looking at them a while back and the center sections did look close to the same. I will start looking for the 3/4 and 1 tons and see what rears and gears they have.
