I recently got a set of stock front & rear chunks with 4.88 gears out of a 95 4runner for 200 bucks that I'm gonna put in my 86 before I get some 33's. I'm pretty sure it has a limited slip in the back and a buddy of mine was telling me about a "pop-in" limited slip you can get that just replaces your spider gears. Something like an Aussie Locker but a limited slip/positrack instead of a locker. I need one for the front 7.5 inch, Anyone know of anything like this?
