Where can I get paint for my dash panel

One option... The dash has a suede finish, no gloss.
The column door is a 4 screws easy sample. If take it to your local SEM dealer, They probably can custom mix a quart. This is how I got the 67 model reds.
SEM product is made for vinyl and plastics but it will work on metal too. Its a lacquer base, does dry with a low gloss. Just dry spray the final coat, and don't forget to paint both vents and column cover so a slight mis-match wont show.
