I have 4 wheel caps for the 1973 factory alum. slot rims. I see the rims come as 14 x 6. Does anyone know if i can get bigger and wider? I'm thinking 17X8 and 17x10 for the back. The idea is to use the wheel caps that I have. Would it be as simple as drilling screw holes to mount them on a new set of rims? has anyone done this? how does it look?
