Restoration

Has anyone been able to find a company or salvage yard that cater's to classic olds fullsize like the delta' or holiday 88's? I know here in NY it's been basically impossible to find much of anything in RWD parts anymore. I'd like to bring my car back to full show quality but parts are scarce. I'd also like to find some holiday 88 parts to transplant to modify the interior. Ok I'm looking for the bucket seats and floor shft to be exact.
