Each had its own configuration for cut-outs, depth, overhang, etc... ALL of them had been discontinued by the early 1970's but I can remember walking into my Chevrolet dealer in early 1981 and they still had ONE on the books under a different part number. It was a "catch all" for the Camaro and Nova. It fit, but you had to hack the he!! out of it!!
