I have an 87 YJ with a 5 speed and am in the process of trying to replace all that is necessary. I want to change out the Dana 35 in the rear and the 30 up front. I've checked ebay a million times and a few jeep junkyards, but there is nothing that is in decent condition. Does anyone have a kickass source or idea? I also want to change out the tranny. I replaced the 4.2 with a 97' 4.0 and it doesn't quite match to the 87 tranny. It runs ok but I had to insert a bushing for it to work..
