Plastic Inner Fender Wells

[StealthBird]

The red plastic inner fenders were first developed by Pontiac in 1965, and were used on 1966 A-bodies under option code 522. The creator was Pontiac materials engineer Josh Madden, who also developed the cast polyurethane-enforced Endura bumper (introduced in 1968) and the thermoplastic front grilles (1966 GTO). The red inner fender liners were not popular at the time, but were definitely eye-catching. They were available with any body color.

In 1967, Oldsmobile borrowed Pontiac's idea and created injection molded red inner fenders (not just liners, but entire inner fenders) for the front wheelewells of their 1967 W-30 442.
