There seem to have been two colors of interior paint for 53, used on dash, doors, cab,seat frame, etc,. One is a semi-flat, brown-gray, with a slight metallic tinge. The other interior paint is a semi-flat, Charcoal shade. Both are lacquers as original. The steering wheel, the horn button, column and shift lever are a slightly different color, sort of gray-brown and more glossy than the interior paint. You can get both interior and steering wheel paint from Jim Carter and probably other vendors. It's pricy, because you will also be charged a hazardous material transportation fee. I've used Carter's paint, with good results. The lacquer is subject to chipping when struck with a sharp object, which makes putting the interior window trim back on a hairy job after painting. I'm sure with the correct paint numbers, your local shop could get close, but at the time I painted my truck (a 53)I never could get two people to agree as to what was correct. Like all paint, Carter's will have variations in runs, so buy enough to do the job and buy it all at the same time. I've never seen the Charcoal used, but if you want to see what the brownish paint looks like on my truck, cut and paste this URL http://albums.photo.epson.com/j/AlbumIndex?u=1784934&a=13816194&f=0
