Very few 1st gen Camaros came with the spoiler. It's interesting watching the car show judges measuring the trunk spring rods to see if they are correct. It's also a kick to see all the 1st gen fbodies all in a row with the trunk lids up at a car show. A little breeze in the wrong direction and all the fake spoiler cars trunk lids slam shut in unison. The correct spring rods are worth a fortune. Don't bother checking your Firebird trunk springs because you will not find the heavy duty one. If you have any Camaro parts cars it would be worth a look. Jim
