So I've got Cragar D Window wheels in mind for my 78 malibu sedan, 16x10 on the back and 16x7 or 8 in the front. I highly doubt, however, that the 16x10's will fit on the car. Do I need to raise the rear a tad to make way for the bigger wheels or just get the right offset on the wheel? How can I get the big wheels on the back? Any thoughts would be great!
