I'm in need of the following pieces, as I'm putting in a new floor and frame rails. I'd rather not remove my wheel housing areas so I'm looking for cutouts from another car so I can patch in. Let me know if you have anything that may work. I'm in Canada/US. thanks a million guys.
Auto Metal Direct has good parts but their website seems to be down. Year One is the big player in restoration parts www.yearone.com. Also pick up a copy of Mopar Collectors Guide, it is an information goldmine on Mopar parts supplies and vendors (research carefully though, as all may not be on the level).
thanks for the tip for the wheel tub steel Ian. As a follow up, I found a guy on Cuda-challenger.com. he's gonna reproduce the small piece I circled. Mine will arrive next week.
