install used parts from a junkyard yourself

Lunchbox lockers, like Loc-Rite, Loc-Tite, something like that. It's the kind that replaces the spider gears. Their claim to fame is installation doesn't involve messing with the pinion or ring gears, so no special tools are needed, any decent mechanic can install it in the driveway with regular tools in a couple hours.

They are not nearly as strong as genuine lockers, tho.

thanks for the replies. I'll look into the names mentioned. Also on the junkyard hunt...what am I looking for? How do I tell if a truck in a boneyard has posi...should I aim for the four wheel drives?

When looking in the junkyard, look at the RPO code list in the glove box. You would want to find on that had the codes GT4 (3.73 gears) and G80 (locking differential) listed. Either 2wd or 4wd might have both listed, but I would say that the combination would be more popular on the 4wd (at least in my area).

if you are going to the junkyard to get the whole limited slip set up then it would be cheaper to get a lunchbox locker. If you go to the junkyard you would have to get a mechanic to install it. To do all the backlash and what not. The usually charge a pretty good bit to do all that.
