I am wondering if anyone knows the paint code for the gray paint used on painted Magnum 500s in 1966? I am not looking for exact concourse, I want to paint the set I have for use on my 66 Coupe. I have some grey lacquer primer and partial can of PPG DDL9323, enough to do the black out. I was thinking of painting them with the primer, black paint and then coat with the Matte Finish lacquer clear sold by Duplicolor at the part stores... any ideas?
