His did your paint job come out?Both Ames Performance and Performance Years carry the interior vinyl dye paints that can also be used on the metal trim. If you call them, I believe they will send you samples in order to get a match. I believe they are Omni Pak GM reproduction colors. Omni Pak is owned by the Krylon Products division of Sherwin Williams, so you might be able to go to local store with a high quality photo for a match.
I have a different color interior than you but used a spray can from Ames that was a close match.
