1968 Pontiac Grand Prix
This would be last year that the Grand Prix would be based on the B-body.

1968 Pontiac Grand Prix

Redesigned again in 1968 with a peripheral front bumper, pointed nose, split grille, new tail lamps, new interior and instrument panel. The rear side window lost its sharp trailing edge, a Grand Prix signature design. New wheel discs and pencil-thin whitewall tires were also introduced. This would be last year that the Grand Prix would be based on the B-body.

(For example, the combination EC on a Pontiac would indicate the body finished in Aegena Blue Metallic and the roof area in Cameo Ivory.)

Corvair paint code plate is on the left cross-rail in the engine compartment. Corvette paint code plate is on the instrument panel brace, below the glove compartment.
