I know there's a great write-up by QMan already in the manual. but I just did this swap again this last weekend, and took a few pics while I was doing it. and thought you guys might like to add them to the write-up.
pieces to save from 3.9:
LSD carrier to swap from 3.7 to 3.9:
LSD carrier with 3.9 Ring Gear on it:
All assembled but stub axles and rear cover:
No grinding was necessary on either case. one from an '85 EA82, the other from an '88 EA81.
