You would need to change some of the front end to Camaro to do it. I'm not sure of the fenders are different, but you would need the Camaro front end and hood at least. You would end up with a Firebird that looked like a Camaro. Why? It would seem to me that you would be better off the sell the Firebird and get a Camaro if that is what you want. If your flip up headlights aren't working, go to Top Down Solutions banner and click on it. Lon sells kits to repair the gearbox on the headlight motors on Firebirds.
Why?
in his early days my son was racing a camaro with his firebird. they were neck and neck until he closed his headlights. bye bye Camaro. The Firebird beat the Camaro.
