yah the overall rear end is the same, just a different ring and pinion gear and a limited slip carrier. either way the part you want is the carrier, its pretty easy to swap the gears themselves. I think some of the newer gen rears will work as well, but can't be sure on that. obviously if you swap the trans and rear then you won't have to change the ratio.
says that its already swapped in your original post, do you want to swap it or is it already changed? If you have an EA81 then I wouldn't swap it. the EA82 introduced a few small issues and you have to change timing belts. not worth it for 8 hp or whatever its got over the 81. if your planning on putting money into a swap, check out an EJ swap so at least you can get a proper look at your options. the extra cost to do an EJ would probably be a bargain compared to the gain (if your going to swap anyway).
Yea I'm doing the swap only because I have already bought all the parts to rebuild the motor and to put the Weber on it, and I got the motor for free soooo yea....., I'm just building it to drive back and forth to work, still have the 4 speed in it but, I really just want something a little different.
So yea I'm just ganna look for another carrier with the spiders in it and make that my Lincoln locker so I can swap it out if I need.
