1969 was the last year of the GTX Convertible. In 1969, the GTX's sales dropped when the Road Runner was also offered in a convertible body style. The GTX received minor cosmetic changes to the tail lights and grille, as well as the side marker lights. An optional Air Grabber hood (standard on Hemi-engined cars) featured functional openings on both sides of the hood that were controlled from the dash.

The 1969 GTX had black lower body side paint in place of the previous stripes. The standard 440 V8 was still rated at 375 hp (280 kW). Total Plymouth production included only 701 GTX convertibles in 1969. Of those, eleven were equipped with the 426 Hemi; four were 4-speeds and seven were TorqueFlite automatics.

These kits are factory sealed, but the boxes do show some moderate shelf wear.
