Looks good. I found that my OV-15's PC socket actually is good and it was just the PC i was using that got stuck in it, not the socket, since other PCs don't get bound up in it. Just need the terminal block now. If you or anyone else has a Cooper or Westinghouse terminal block from a roadkill fixture please let me know! Thanks!
I don't think those would work. The ceramic/porcelain base is actually fine, the terminals are just rusted beyond belief and won't come out so I'd have to drill them out. If i end up with a new terminal block I'll just use the new terminal block though.
