1968 Dart 270 "beater" 4-door sedan LH41

I'm looking for one I can use as basic transportation and fix up as I go. If it runs and drives OK, is street legal, has an automatic, and costs $500 or so, I'm happy. I work in electronics recycling and computer repair, so maybe a cash n trade deal can be worked out.
As an example of what I'm looking for, I've attached images to this. Thanks for your time and consideration.
