need front hub for 65 dart

If you ever do need to separate the drum from the hub, on later models (~68 up?) just throw the drum down on a hard surface many times and the hub should drop out. I have done it on asphalt parking lots (out of view).

Earlier models ('65 I know) usually have swaged studs, meaning the factory crimped the studs at the drum to help hold it on. You can grind the crimps off with a Dremel tool or hacksaw. There was even a special cutting tool for that. I once beat the crimpled studs thru w/ a hammer in a JY to recover the hub from a bad drum. Worst-case, you could cut off the studs flush then drill them out.
