I ran across a'53 1/2 ton that was a power company
truck & it had dual spares ! I inspected the passenger side fender dimple closley & it looked just like a factory stamping. This is the only truck I have seen in 25 years that appeared to have factory dual side mount spares & I believe it was a super rare "on request" only option. Good luck finding one ! Metal Man has the info. to convert the smooth fender to the dimpled style
