I meant the ebay pic is named "52-1952-Chevrolet-Chevy-Panel-Truck ...."

otherwise I'd think the bumper shape might be a clue and dash layout/holes, not as familiar with the ADs
I knew the panel bodies were built on the floor assembly, I recall line pictures in an old Golden State catalog that showed some of it, including the completed body with front clip being lowered onto a chassis, thought I'd sacanned and saved them, but don't find'em now
