Are the plastic and metal pieces in a '67 parchment interior considered "light" parchment with regard to the spray paint available? I know there is a lot of problems getting the correct shade of parchment in these cars. I haven't seen a paint called just "parchment", but have seen and used Rainbow Industries "light" parchment, but it really doesn't match the soft interior pieces...seats, etc. The parchment door panels from TMI are darker than the spray paint. Did the door panel paint originally match the door panel color at the factory, or was there a shade difference? I've seen a few previous posts and pictures on this subject, but now that I'm about to install these new parchment door panels from TMI, I don't want to have to go back and paint the doors is I'm using the wrong shade paint.
