Hi, not sure if anyone here could help me out with this, but my other vehicle is a 1987 Toyota Pickup 2WD, and I was wondering if anyone knows of a conversion kit of some sort to change my open differential to a limited slip diff. The truck is too good to give up, plus it has just under 300,000 miles on it, so its not worth anything to sell, either, so I'm trying to make it perform as well as it can in the snowstorms that Colorado gets every now and then, cuz the Supra just isn't that great on ice, as I'm sure some of you can vouch for. Any info would be appreciated, thanks!
