There were two sprint packages in '72 (A & B). Package A included special graphics (dual blue/red stripes on hood, blue/red lower body paint, and blue/red rear panel) on a white-bodied car. It also included the USA shield on the rear quarters, the Exterior Decor group (honey-comb grille and color-keyed front bumper, hood, and fender moldings). There were also dual color-keyed racing mirrors, flat brushed aluminum hub caps with trim rings, E70x14 WSW tires and a unique interior (white vinyl bolsters and blue Lambeth cloth inserts, plus white interior trim and color-keyed carpeting).
Package B added 15-inch Magnum 500 wheels and F60x15 tires.
Since the packages did not include a special or high-performance drivetrain, it was not a big seller as I recall. Also this was the early 70's, Vietnam and the related protests were in full swing, and red, white, and blue was not the most popular color combination on the planet. Still, it will be an unusual car if you bring it back to its original trim and should garner pretty good attention at both the gas pumps and the car shows.
