68 Dodge Dart GT wheel hub question...

Hi:

I had to pound out the studs after the lugs stripped on my Dart. The drum and the wheel hub separated. I think I may have caused it to warp a bit. The front driver side wheel is not rolling smoothly.

Any ideas on where to get a new wheel hub/drum? I can't find it anywhere...

If not, I'll just convert to front disc. Any recommendations on that?
