zl1 camaro

I need help again, I found out my car came with painted wheels & dog dish cap. For the life of me I can not find what size wheels should be on this 14 x 6 or 14x 7. [1966 442 post car - sport coupe.] The next question is I need to buy some wheels & poverty caps. Does anyone know where is the best place to buy these ? I know I will need to get them painted of course. I assume the wheels are just painted on the outside not the back side like chevy did ? FUSICK has the caps for like $90.00 each. I can buy a complete set of wheels & caps for like 855.00 from parts place. I guess that's not really a bad price, Does anyone have any other ideas ?? once again guys,, Thanks much
