I've actually got my eye on a 71 Challenger now. Considering the same build to the 71 as I did to the Charger, Complete restomod, Reilly suspension, Viper motor, tremec tranny, custom interior. But I would sell it when I was finished, same quality as the Charger.
We are keeping the 73 as is, my brother wants to keep it as stock as possible, if you can call a 73 RT 440 clone stock.
