I have the black street charger, the red super charger the dukes charger and the buddy baker charger. not sure but from what i have seen the Richard petty charger was first then the buddy baker charger. Looking at the floor pan from the buddy baker car and the black street charger they are 99% the same other than in the street charger they tooled the tunnel as to look like carpet and the fire wall does not have the place for the battery. So other than adding the blower and interior parts and wide rear wheels and removing all the NASCAR parts its the same kit. So in thought the run would be petty/baker NASCAR then the street charger as they are cast the same with very little change. Then the dukes charger and last the super charger. Like i said i have all 4 kits and looking at them that's the changes i'v seen.
