ONLY early 67's did not have the dimples. A rather rare find if you ever see any. Scott Fuller can make you up a couple for your 68. His systems are the absolute best out there but they are more in line of Concours Trailered and Thoroughbred, not so much the perfect choice for a daily driver (IMHO). The hardware he sells (clamps, hangers, tips etc.) are all 100 % perfect for all classic Mustangs.
