71 Scamp parts

Just picked up a 71 Scamp project. I need a few things:
-interior door panels
-bench seat hinge covers
-dash pad
-tuff wheel adapter
-good grille
-trunk lid aluminum trim
-tail light lenses
-large ball joint upper control arms
-under chassis 440 headers
-slant 6 to big block mounts
I'll probably ad more to the list as I go. I know I can get stuff new, just trying to save a few bucks.
Thanks
