Does anyone know of the original process for painting? Would cab interior be done separately from the body? My paint code is T which is candy apple red and the current duplicolor spray can is pretty close on the interior, but way off (too red) for the exterior. GM Victory Red is really close to Rangoon Red (there's a cool website which gives all the RGB numbers) and is a pretty close match to the exterior. Given that rangoon red is code J, I could see it an easy mistake if painted separately.
