If you have the original glove box door still on the truck, there will be a list of RPO codes on a decal on the inside. Check the codes against this list it should tell you the diff size, gear ratio and posi or not.

The stock axle in there is a 7.5" ten bolt. It was adequate for the 4.3 V6 if you didn't stomp on it

Later S10s with the ZR2 offroad package had the 8.5" ten bolt and disc brakes. It'll bolt in, but there my be differences like driveshaft length, ujoint usage, etc, but its as direct as you'll get.
