Hey Mike, I dug thru my old PPG book a couple of months and posted all the exterior colors Alfa has used under Restoration but had nothing for interior or trim. I doubt SEM will have a spray can close to the color you need but if you can spray it yourself the paint store can custom mix SEM in quart cans. I would remove a small piece and have them match to the color on the back side of the piece rather than the faded front side. As for wheels, I did some spot in work on a silver 86 Quad and still had a pint of silver b/c left. It looks like a good match for the bumpers and wheels on my 85, I've already painted the bumpers and am trying to get the wheels done before the Italian car Sunday Drive they are having the 14th of next month.
