I'm trying to help a buddy decode some of the options on a 70 GTO he recently picked up. The codes are TDD, EWA, & AXU. Also, the PHS docs show PK2 G-78 14" w/w tires. Does anyone know if these were these the standard tire on a 70 GTO? I was expecting a standard F-70 14" like a Chevelle.
Any help would be greatly appreciated.
