The Camaro plastic housing has 4 screws that go in straight, or horizontal to hold the top and the Nova has these screws going up, or vertical. Yours looks like the flange is made for the screws to go up. Also the Camaro plastic housing wraps around the edge next to the ash tray and there are holes for it to fasten next to the ash tray. The Nova plastic does not wrap around, so no holes next to the ash tray.
