best way to verify posi is to get both rear tires off the ground, then spin one of the tires... if the other tire spins the same direction you have a posi.
While you're off the ground, make a chalk mark on one of the rear tires and spin it thru one complete revolution while watching how many times the driveshaft turns... if it's just a little more than 3 revs, it's a 3.07... a little less than 4, it's a 3.73... a little more than 4, it's a 4.11... good luck. ------------------ '72 short step, 350, 700R4, tilt, ps, pdb, a/c, lowered coils, etc., other work in progress...

I had a 71 3/4 and it had a Dana 60 in the rear. This can be checked by looking at the casting mark on the lower right side next to the diff cover. It should just have a 60 there. Could also be a Eaton type, these have a drop out center section from the front. In half tons, I have seen both the 12 bolt and dana 44 rears.
