I put Cragar S/S wheels and BFG tires on my 64. I worked with
www.newstalgiawheel.com to buy them and went with what they suggested and I am glad I did. I used 15x6 Cragar S/S wheels with 3 3/8" backspacing and P21570R15 BFG tires. I was hoping to go 7 inch wide wheels and larger tires but Newstalgia said I woud have problems, and they were correct. This has been a perfect combo and the price was right. They came mounted and balanced and ready to bolt on the car.
