67 wheel options

I'm looking for info on the factory wheel and/or hubcap options for my 1967 Grand Prix. I know of the 8-lug wheels, but can't find anything on other options?

yearone.com guy has stockish styles
wheelvintigues.com? has bigger sizes in stock styles.
summitracing,jegs are also good.

anything 5x4.75 will work. 5x120mm will not. you want a 4ish in backspacing to have a decent stance.
