JC Penny's had a brand called AF/X Racing Team. They had wheels, slicks, headers, tachs etc. I believe they were made by different manufactures for the catalog giant. BBBenny has a killer pair of slicks that have the Foremost JC Penney name on them. I have an AF/X Dixco Tach also. Used to shop there in late 68 before we had enough money to buy speed equipment from the real "speed shops." Around 35 years later we finally realized it was pretty much the same parts for a little less money.
