I used Rustoleum Dark Bronze Metallic #7272 for the interior of my 53 one ton, and I was pretty happy with it. I ended up using about 10 cans, and it didn't cost that much. I found also that a Subaru color, Misty Dawn Metallic #35-40840, was pretty close.

I am currently digging back in to a 1953 3800 (one ton) with a nine foot bed. I've owned it since 1979, and drove it until 1982 (or so). My wife got me involved in restoring it back in 2002, got the body removed and the frame redone, then things came up. Now I am retired and starting again. If anyone is interested I have photos on Imagur (
