I have a 1979 Chevy Malibu with a 8.5 Grand National Rear End in the back all stock I was wondering what is the correct or a good backspacing for Wheels I'm trying to buy 17 x 8 on the rears I see they have4", 4.5" and 4.81" backspacing will the 4.81 inch backspacing be good enough I don't want them to stick out too far from the fender Wells
