F350 super camper special
I am restoring my Father's '74 F-350 Super Camper Special. It originally had 16.5 X 12 tires on the back. They were referred to as supersingles. Over the years, the rims that fit these tires have ben sold, lost, something. Anyway, does anyone know for certain what width of rim was originally on the 16.5 x 12 tire? I've been told that it's a 9.75 width rim. Is this correct? And any idea where I might buy a set other than going to a bunch of swap meets? Thanks!
