Car looks high in both the front and back from stock, is that your intent? 4.5 backspace on 14x6 rims was standard on the chevelle SS. 4.5 backspace on 14x5 rims for the Malibu. What rear is in the car? Do you have the wider rear from a 68 and up. Then if you have repo quarters on the car the lip extends further to the inside than on an original quarter.
Bottom line make sure there is no interference with the fenders or quarters.
