When i was looking at frame connectors there were different listing for cuda and challengers, I dont know if they were actually different, but if they were the same why wouldn't they just put them under "e-body". Either way, If they are different, they cant be by much. Chances are you can make them work with a little patience, a welder, and a cutoff wheel. :laughing: Hopefully someone that has experienced this can shed more light on it. Good luck.
