There is a difference in the front hubs single vs duel. At least on my 46 1 ton,and the rear hub flange placement on the hub. This has to do with front to rear tracking,But bearings are the same. This is talked about on the Pirate 4x4 forum. Look under HO72. There's a bunch about it.
They also talk about wheel mount to wheel mount diff in some of the newer stuff.
