are the brake drums interchangeable between hub piloted and stud piloted assemblies? Thank you much

i would say no, stud pilot's have much smaller inner studs so the drums have smaller holes, weather you would be able to machine the holes bigger or not i don't know
serozhah Thanks this. -
I just checked and it looks like the brake pads seat against the drum pretty tight when the brakes are set. I hope it will be ok...
well, this website:
http://www.cumberlandtrucks.com/wp-content/uploads/2014/11/Brake-drum-Pilot-Hole-Mounting.pdf
suggests that they sell drums with one size hole for stud piloted and hub piloted studs. They say smaller stud is ok, because the drum is centered by hub and not studs. You think that sounds right?

Some are interchangeable, some are not. The stud holes are obvious, but as long as the studs fit through the holes, it's not as issue. The issue is the size of the big center hole of the drum and if your hub has the pilot tabs for it. if the drum fits snug on the tabs, and the brake shoes contact the drum where they are supposed to (not hanging out on the inside or rubbing the outside), it's OK. Then check that the tabs on the hub are long enough to center 2 wheels as well. Some stud piloted hubs have small tabs that only center the drum and you cannot run hub piloted wheels on them just by swapping studs.
