You probably are looking at a Salisbury differential. Easy way to tell is if it has a drain plug. Regardless, Power Lock was an option. One way to tell if you have a "posi" rear in a car is to put it in neutral and raise the rear off the ground. If you rotate a wheel and the other wheel rotates in the same direction it has a locking feature built into the differential. If the wheel on the opposite side rotates in the opposite direction it does not have posi-traction. If you don't have power lock it can be added by someone like Curt Hamilton.
Numerous ratios are available for the Salisbury, if a gear change is required. There should be a tag, attached by a cover bolt, indicating the number of teeth on the ring and pinion.
