Will a 68 posi unit fit my 72?

A guy on ebay has a posi unit frorm a 1968 3/4 ton. He says it should fit my 1972 GMC 3/4 ton if I have 17 splines on the axle.
Does anybody know for sure?

If you have the HO52 corporate axle (non-Dana),then they are the same.I believe the splines are all the same.Anyone know better?
