69 camaro wheel advice

[jonesbs9]

ive got a customer thats wanting to go kinda old school on a 69 camaro. like a 16 inch wheel with a big sidewall, anybody have a car at home that hasnt had the p-t treatment yet that can give me an idea on size and back spacing to get as big as i can within the stock wheel opening..the car makes more power than a little street tire will handle, but hes going for the look. im thinking something like a 16x8 or so in the back with a 265 or 275 tire, not sure on the front, car has 4whl disc brakes but just little dual piston baer. should have any brake clearance issues...pics would be nice
