I searched and couldn't find this, I found everything else about LSD's though. So here is my question. I have 91 trooper without the LSD and I want to find one for it. What models and years of Isuzu's SUV's can I get one from. and do I need to change the whole rear end or just everything in the Diff. My local salvage yard has a 2000 with a G80 but they say it won't fit. I thought I saw somewhere on here that all troopers after 88 had the 12 bolt rear end. Any feedback you guys can give would be greatly appreciated. Thanks
