Tires are 315/60-15 so right at 30 inch diameter. He originally had the Dodge SS hangers in there so the rear was moved back 0.700 but he didn't know it. When the chassis shop put the new rear end in they put it in the stock location since they didn't know it should be moved back. I can fix it with some tricks. I assumed Calvert would tell him no problem and build a custom front segment but maybe they are too busy to deal with one time orders or something.
