I don't, but I don't think that color should be too hard to match. Be sure to look at a hobby store where they have Testors paints, as well as of course all the obvious hardware / auto parts places.

My brother had a '74 Continental once... at the time he got a number of accessories in the matching color, including a Schwinn Approved security cable exactly the same color as the bike. He sold the blue Continental in the late 70's, but he still has the cable!
