Wheel bearing/hub Question..

[Rowdy]

Hey all.
Im getting close to shooting (painting) the PT Stepside project. The paint came in today, and that sure is a motivator to kick things into high gear in getting this thing on the road.
Meantime, the rear passenger hub is missing a stud (where the lugnut goes) and both (drum brakes) are rusty as heck. I found a pair of Brembo drums for 70 bucks new...
My Q is... I like to upgrade things when there are better than OEM options available... I need to fix that broken stud so I just plan to put new rear hub/bearings in it. Is there any HEAVY DUTY or better than OEM replacement hubs/bearings avail out there? I cant seem to find any. That may be because there isn't any available, i dunno (shrug).
No, I don't plan to convert anything to discs back there or nothing like that... I'm not looking for a brake upgrade... just a wheel hub/bearing upgrade. If nothing is avail, I'll go with OEM replacements but figured I;'d ask here first.
thanks everybody!
