The fixed B-pillar on this first-year '68 model marks it as a coupe. After December 18, 1967, a pillarless hardtop body style was added to the Road Runner lineup. Coupes outsold hardtops 29,240 to 15,359. Oddly, aside from the pillar, there are no other visible differences between the two body styles, and they share the same windshield, roof stamping, and back glass. This coupe was a 383 four-speed car, and its VIN begins with RM21. Road Runner hardtop VINs begin with RM23.
