Nothing new on the interior. I put a pair of 69 Camaro buckets in it for now. Except for the B&M shifter and the dash pad, its bare bones steel inside. We took it to the local cruise in tonight. I drove the '39 and my son drove the Chevelle. No interior and rusted quarters, it still drew a lot of lookers.
Bill you are correct the paint code is KK. The interior was black, and almost perfect. The guy that had it before me got hard up for cash and sold the interior for $250.00.
