Hey Russ Davis I was on ebay the other day and there is a guy selling a bunch of challengers to restore and I think he stated in one add that he had some parts cars as well as other parts.
I will look to see if I can find the link maybe he might have something or you could a whole car for the price your looking at in parts.
I couldnt find the guys add on there but he post a good bit.
You might want to try
http://www.autometaldirect.com/ they seem to have alot of good metal parts and a lot that I have missed since being out of the Mopar world and car world for six year.
Try wild cat auto as well they are good to deal and not to bad on prices. I would look at dessert valley auto and stephens perforance.
