I am pretty sure I have verified the information on my door tag. I know a color but I don't know "the" color that was used to paint my interior originally.
My Tag (second row):
115=wheelbase;
K=Boxwood green;
f103=GVW of 4500 pounds;
63=interior trim of light green/medium green vinyl;
C=transmission=3 spd manual;
09=rear end 3.70.

3rd row:
045000=;
114=;

The previous owners did a lousy job rattle canning the interior black (did not bother to cover **** or remove anything (backside of the seat belt retractor was still green, front side black). The exposed metal on the doors are still the factory green color.

 

Simple. The interior metal matches the exterior color.. Boxwood Green.

 

is there an interior equivalent or are you saying use the same color?

 

The latter.

 

Anything metal on the inside was painted the same colour as the outside.
