Dave, I just found a 1972 project hugger build thread.
http://67-72chevytrucks.com/vboard/s...d.php?t=371685 Your 72 must be a St. louis truck. Maybe you lettered the 71 Fremont truck to match the 72 hugger St. Louis truck??? Just curious and it helps my research on the assembly line markings at the various plants. Thanks for your time on this.
