Bryan Durdle has a Facebook group called 1970 Coronet Club. There are always serious buyers on that site. B-Body Mopar is another good one. Be prepared for a few idiots with no cash to chime in and be dolts, but I have known of cars to move fast to guys who really desire our model.

BTW, I would already own your car by now if I'd had the dough. A remember you looking to sell in the past. I've been drooling over that thing for years. Best of luck if you decide to go that route.
