1973 duster fit 20"s??

If you fit them I would be very interested in seeing the result.... I want to fit 14 inches rotors for brakes in the future and that would mean at least 18'' wheels. Really decent braking demands huge rotors and large calipers... I know I know ceramic carbon rotors are smaller and way better than anything else.. but they are so f@cking expensive I can only dream about them.
