Rear diff interchangeability
I have a 78 that I want to swap out the rear end in, but I cannot find anything that will tell me what years are interchangeable with it.

Re: Rear diff interchangeability (Glensgages)
If anything is going to be making you be towed home, it's that trans. Don't expect the stock 82 700R4 to last too long. They're pretty weak...Our 82's has gone out on us twice now. And I don't think it's got 90,000 miles on it.

I swapped out my 1976 differential with one from a 1964 that had original 4.11's. All I had to change was the yokes and it was ready to go.

Glen, the mounts to the frame are different on the different rears. I think the yokes and the half shafts are different as well.
I wouldnt worry about the DANA's to much.

You can also put the aluminum cover off the 80-82 on the 65-79 housing. You'll have to mod the rear. We are currently doing one. We are also dropping a 5 speed in the car. If i can ever find my digital camera i'll take some pic so you guys can see.

Re: Rear diff interchangeability (Berserker78)
1980-82 interchangability: Automatics share the same side yoke/half shafts on 80-81, manual trans cars' side yokes/half shafts are beefier/larger. Not 100% interchangable.
I'm assuming on '82, since only automatics were offered, the side yokes and half shafts are same dimensions as 80-81 auto cars.
