Aftermarket 17" Wheels for a 1969 Valiant

i put 17"s on my car but i am running the later model disc brakes the track width is probably different so i cant help you with the offset. you can upgrade the brakes for less than the cost of tires and rims you are looking at. its a six banger car, a brake upgrade certainly wont hurt the value in anyway, if anything it is going to help it.
