I can get you guys intouch with Ted Steven's of Steven's Performance with the AMD stuff.
If you see him at the show, he should have some parts with him, just tell him your with the moparts/cuda-challenger forum and would like to save. He has already left, so he may have a trunklid and others parts at vegas and van nuys shows.
As for the trunk fillers, if ya wanted them, $75pr (parts are always cheaper if I don't have to package, ship and other stuff) to pickup at spring fling. I sell in the parking lot before the show sometimes and can arrange something.
The seat tracks won't be for sale, as they are nice enough fo rmy ride.
