if your looking for tire size most were 13" with 4 lug wheels.....and some 14" with 4 lugs which should be a six cylinder car.....V/8's cars could be either 13" or 14" as well on a five lug bolt pattern....not to wide maybe 4" or 4 1/2 wide in the early 60's....
I have acquired a 64 comet but it has after market rims. It is a V8 car. I am looking to find stock rims for it so was trying to find out the specifications to help track some wheels down.
