Check out: http://www.artmorrison.com/ While there have been many Camaro subs successfully installed, I would recommend a "factory kit". Also, if you have any ideas about eventually doing the back half, you could end up with a cobbled mess. I bought my 55 with a factory front & back half installed (cobbled mess). For a few bucks more, you can get a full frame replacement with any configuration you want. The 55 is now sitting on a custom built 2 X 6 frame with a 4-bar setup & air-ride... this is the way it should have been done to start with & costs lots less in aggravation. Don
