stock replacement wheels, hubcaps that fit?

[cortcomp]

I'm going to need to pickup some oem looking wheels for my 66 c10 (link of what i was thinking below). I searched but didn't see any specifics, sorry if this was covered.

I'm thinking of running 15x7s (thats what seems to be on it now)..does anyone know the closest to correct backspacing?

I'm looking at something like the hubcap below, has anyone tried them on newer wheels?

So, i guess, what new wheels have you guys used that are 15x7 and take the repop or oem center caps?
