1972 GMC 3/4 ton rear axle ????
A friend of mine (72LEVI) picked up a 72 3/4 ton GMC with a Dana rear axle. My question is, which one is it, a 60, 70 or ??? I don't know them a part by looking at them. Also I always hear of 3.54 gears in these axles, are those the only ones they came with?? Are they worth keeping in a truck?? If it's a 60 or 70 it should have lots of aftermarket support right??
Thanks.
