Yes, Yes....I to helped a friend do that very thing to his 70 318 Challenger...(When we were done his looked just like an RT as he also added the exhaust, markings and even the rally dash...but funny thing was..he never updated the engine...he loved his 318)...just trying to make a point, that back in the day you could still tell the top of the line RTs from most of the base line models.....
