[quote=Doug 57]When I said none that I know of I meant that about 16" split rims.
Were your wheels just 16" or were they also split rims?
When I bought the truck, it had 16 inch steel rims from a more recent model. The spare was mounted on a 17 inch split rim. I would assume that that 1966 C30 originally had the 17 inch split rims.
