Need to know what kind of hubs I can use?

Remember when you take the cotter pin out and unscrew the nut taking the drum remains off the bearings come out also so make sure you have them put in the same with bearings races and seal and Do Not over tighten when installing the nut just snug it with pliers and spin the drum a couple times and snug a little more only if need and if the lock clip dont line up back the nut off a little to put the cotter pin in I have seen these overtightened before and it will burn the bearings out quick
