Phoenix graphics makes the door decals. Best bet with the rear wing is a fibreglass repro from Hawks. Good luck with the owners kit. They have been selling for ridiculous money these days. Check Ebay. They come up for sale once in awhile
I am about to sell my owners kit, its in great condition (box has a little wear on the back top horizontal edge, not deep wear), has everything but the front windshield decal (its on my car, bought it that way) I am asking $1500.
