1974 Challenger was originally gold with a 318 and automatic. Has been repainted to silver with a vinyl top and Rallye gauges added. Had a tach mounted to the steering column at some point. Probably at the same time the motor and tranny were removed and switched up to a 1975 400 with a high lift cam and a 1970 A833 4 speed and drive shaft. Evidence shows that a roll cage, and fuel cell and battery box, which were mounted in the trunk, makes me believe this was a drag strip car at some point. No build sheets or or fender tag, only VIN. Both rear quarters have been reskinned/replaced and the interior has been completely redone including the dash which does not have the proper rosettes holding the VIN in place. I can last place the car as being registered in Missouri in the 80’s. As I cannot legally get previous owners names, I’m stuck at this point. Any and all help is appreciated.
