1977 Nova Parts and Restoration Information

The Nova saw more minor changes for 1977, including a more rounded gauge cluster, flatter dash panel, increase in small trim pieces.

You could also get the model in a handful of additional colors. Heavy-duty suspension and F41 sport suspension options were also available for the 1977 Nova.

The Nova SS was discontinued at the end of the 1976 model year, but the basic premise remained with the addition of the Nova Rally, which could be purchased through dealerships with order code RPO Z26.

The Nova Concours continued to be produced for 1977, this time with it’s own brochure separate from the other Novas. New wheel covers, a fine mesh grille, stand-up hood ornament, and wider wheel opening brightwork were features to look forward to on the updated luxury model.
