Well given the new challengers use a 5 x 115 mm bolt pattern and the older mopar stuff is 5 x 114.3 (5 x 4.5"), you may get them to work but it is not ideal. Also set up for 14mm studs, not 1/2". Plus they are positive offset wheels (+26mm factory I believe for a 20 x 9" wheel for the SRT8, not 100% sure on that offset though). I think you'd want a non-positive wheel for most mopars. Maybe a set of wheel adapters might work but I'm leary of using anything like that myself. If you do get it done, post pics
Good luck!
