Thanks Don,

As you may know I am working on a 40 gmc. There are lots of similarities and differences. The 41-46 NOS GMC super deluxe heater I purchased off of ebay was not krinkle, or hammered finish. It matched up closest to "Dark Bronze Metallic" Rustoleum rattle can.

The interior of my truck had been brushed and painted by a previous owner. There is little evidence left to suggest the original colors. One part of the interior that was not taken down to bare metal is the metal seat bottom surround. Under all the primer it is painted Brewster Green... the same color I have found on the fire wall, and the underside of the hood.
