As far as I know nobody made a replacement hub for those, just a hub and drum assembly from mother Mopar and they discontinued them decades ago. When looking for a used one take particular care in making sure the outer bearing race is tight in the hub. I've literally seen hundreds of those with spun races. '60-72 models will interchange, but, keep in mind that '60-9 had left hand threads on the driver's side, and '70-2 were all RH thread. If you get the lug nuts with them, not an issue. Just remember what you have when it comes to removing a wheel. Lots of tire shops don't know then made LH threads on some cars and will accidentally wring them off. Also, the '70-2 version were finned drums, whereas the '69 and earlier were smooth. Interchange them in pairs for even heat dissipation or the brakes may pull to one side when hot.
