CABRIOLET
Chevrolet's vinyl roof cover was an option that was available on Monza
Towne Coupe, Coupe, and Sport Coupe for all 6 model years while Pontiac's
vinyl roof cover was available on Sunbird Coupe and Sport Coupe models for
a 5 model years. Chevrolet called the option a Cabriolet roof cover while
Pontiac called it a Cordova roof cover. With this roof cover came a smaller
rear side window which Chevrolet called an Opera window while Pontiac
called it a Formal window.
For 1975 the roof cover of the Towne Coupe literally 'covered' the entire rooftop including the A (windshield pillars) and B (behind door) pillars of the car. For 1976 and beyond, the Cabriolet roof only partially covered the roof of the Coupes, the back half to be specific. Pontiac offered a full Cordova top for 1976 and '77.
For '75 and '76 the Cabriolet roof was an option package (RPO Z23) which included the half roof vinyl cover, bright aluminum rear trim panel, opera rear side windows, bright moldings around taillights, special instrument panel pad and 2-spoke steering wheel with added simulated woodgrain vinyl insert. This package also featured a few items found in the Sport Equipment Option package including upgraded interior trim, black body sill, bright and black windshield and rear window moldings, body coloured door handle inserts, and the quiet sound group.
From 1977 to the end of Monza production in 1980, the Cabriolet padded roof cover
was a stand-alone extra-charge option (RPO Code CB4) which featured the half roof
cover and the rear side Opera window.
Pontiac, in 1977, offered both a full Cordova cover but also a Landau cover which
covered only the back half of the roof. Both the Cordova and Landau Cordova roof
cover were available for 1977 but you could order the full cover with either the full-
sized rear side window or the smaller Formal window. Pontiac dropped the full
Cordova for 1978. The Cabriolet and Cordova roof cover's vinyl texture pattern was
called Levant Grain and seven colours were available each model year (with 1975 Monza being the exception with 9 colour options - see chart below).
