66 Dart GT HT Whatsitgonnabe?

Unfortunately it wasn't one of the prettiest but not one of the worst either. It'll do for now. I can identify it quite easily when I want to replace it because some previous owner has used a pipe wrench to remove it, making ugly markings on the outer edge. Not far enough in to damage the seal, though. I have spare seals, though, so I'll replace that too when I get (or find) the new piston.
