Maybe someone here can help me identify a taillight bracket I have? It looks like it has a casting number of # 3654353. It takes the '40-'53 style taillight. It looks like it is angled so it would bolt to the driver's side of a single unit (panel) type body, but yet is different from the taillight stand for my '40 1/2-ton canopy express. The casting number falls into the range of numbers that would have been used in 1940, but yet I can't find this number referred to as being used or even discontinued in my '39,'40,'41,'49,51 or '58 parts books. TIA !
