Several owners where asking about getting parts for their cars and I suggested Cleveland Pull a Part, an auto salvage company out of Cleveland. They deal with new cars like the Challenger, Charger, Mustang, Camaro and Corvette .
Check their ebay store front here, make sure Challenger or the car make of your choice is selected. I also look for Buy it now items before going the bidding route.
Depending on what you’re looking for I always seem to have OEM take off parts from my 2014 6 speed laying around taking up space. Rims, Suspension, Shifter, Audio components, Grille surround
