Whizzerick,
Glad you had the number for permanent red, because I don't. Are you positive your truck is forester green? Because it looks much lighter than the forester green paint I have. I noticed yours is a 53, that year forester green was not used, juniper green was.
For the original poster - seacrest green was also available in 49 as an optional color. I will try to email you a scan of the color chips I have for that year.
