1967 Plymouth Belvedere GTX 440 Convertible

A sub-model of the Belvedere, the GTX debuted in 1967 and took everything Mopar fans liked about the base car and ratcheted it up to muscle car status. Featuring heavy-duty shocks, six-leaf rear springs, front torsion bars, and ball joints, this optional setup enables the GTX to handle more aggressively and ride better than many of its contemporaries.
