Not all 10 in drum brake hubs are the same. It depends on what drum your hub originally came with the hubs are offset different. You should provide the heigth measurements of the hub you are replacing to make sure you get the correct one
With the hub sitting inner bearing side down on a flat surface, it measure 2 and 5/16 inches from the surface it's sitting on to the machined flat surface around the studs.
If you turn the hub over, outer bearing side down, it measures 2 and 7/16 inches from the surface it's sitting on to the flat surface around the studs.
4 and 3/4 inches high overall.
I also found the numbers 34736 on the inside between 2 studs, and a pentastar and D15 between the next 2 studs.
