I know that the neon people like to take the small bolt pattern mopar (5 on 4") wheels and put them on the neons (5 on 100mm) and they seem to work, but that is a different combination of bolt patterns than these. I think the main concern is going to be spacing and the offset from the wheels. The charger 18's might work (doubt it though) but I am almost certain the challenger 20's won't work. I think that either wheel will look funny on a classic e-body though, but that is just a personal taste kind of deal.
