As an Impala guy (owned many 68 SS427 disc brake cars), I can tell you 100% that there is no 15 inch wheel that will clear the 68 4 piston calipers other than the DC Rally wheels. The guys who are running stamped steel wheels on 67-68 cars are running Corvette rotors and doing some non-stock modification to run them. If you are interested, drop a note over at Impallss427.com and ask what they are doing. The 68 and 69 15x6 stamped wheels were only available one drum brake or later single piston caliper applications. Those 4 piston calipers are massive and the 15 inch steel wheels will not mount on the hub/rotor assembly without rubbing. That is why you find black painted DC wheels on several disk brake full size cars. They had full wheel covers on them and that was the only wheel that would clear the 4 piston deal.
