Looks a lot like Henry's old car that was written off due to damage down one side (truck drove past too close during the night and didn't stop) and re-built to a high quality by someone. Drivers side I think?
Might not be the same car. Henry Halamaj (spelling?) was his name. It was not that bad. Just bent sheet metal down one side. But the insurance company wouldn't even try to repair it and he did not have the skills.
Someone bought it from the insurance company and did a top job of putting it right. Quite a few years ago now. I last saw it at SPR and it looked fantastic.
Might be a completely different car as I said. It is just that you do not see many Hemi Orange 73 Challenger Rallyes looking that nice over here.
