I bought some 1946 GMC hubs off ebay, thinking I could use them as spares for my chevy 2 ton.
All I really wanted was the brake drums.

The hubs are different, but surprisingly to me, the wheel studs are different sizes. They both have the same size hole in the hub, but the actual nut from my chevy 2 ton wont fit - too small - on the GMC hub.

should the studs be the same size or is this working as intended, with it being common knowledge that the studs are different sizes.
