7 1/4 rear end axles

I may be able to get a 8 1/4 rear end. Do you guys know if the back plates and 10" drum brakes will fit from the 7 1/4 to the 8 1/4 housing? The axle I found does not have the drum brakes.
Some do. I swapped 8-3/8 from a pickup and it took all the 7.25 parts. 8-3/8 and 8.25 are pretty much the same.
