That $220K sale price probably didn't even cover the restoration labor costs. When I had it I had toyed with the idea of restoring it back to 1968 configuration, but it had been completely tubbed in the back, with a full cage. I even bought a 68 Dart body to use the firewall to trunk underbody section from but the cost was going to be insane to undo all that work. Plus I could not find a reputable body man to attempt it. From the firewall to the rear tail panel - it would have had to have been replaced.
The amusing anecdote from all this is that the money I got from selling the Hemi Dart went into buying this car for 20K a few months later...which I then sold to Steven Juliano (RIP) a few months after that.
