I suppose it would depend on what you intended to do with the car.

Outside of the Mopar circle, most people would have no idea it isn't an RT someone simply upgraded so they could drive it. These days, that is pretty acceptable from most people. If the intent to to drive it hand have fun, it would be a great ride, if the price is right for what it is.

If you intend to take it to Mopar shows and claim it as an RT or just enter it under the modified class, you are not going to have much fun. The Mopar purest will go crazy complaining about what is wrong with it, you won't get a moment of peace. I personally would drive the wheels off of it and enjoy it immensely, but I would not even consider entering it into any Mopar show, in any class there.

The general public would accept it with open arms and you would get thumbs up every place you took it. The Mopar people will hate it and they will hate you for ruining their purest viewpoint. As someone has already stated, it will never be an RT. Can you bear that response? That would be what is in your future.
