Note this is an 81 Camaro, second gen car with the 8.5 rear. S10 rears are about six inches narrower so the whole unit won't work, and the internal carrier is smaller, no help. Third gen rears are coil spring mounted, smaller carrier, no help. Either hit the junkyards and look for a posi, both wheels turn in same direction with driveshaft off or trans in neutral, or buy a new posi carrier and have it installed. Not a low dollar way to do this unless you get real lucky at a yard.
