Does anyone have or know where I can find a pattern for mounting a camaro rear spoiler on my 69 firebird? I do not like trying to guess where to drill the holes. I would hate to mess up my trunk by drilling the holes in the wrong place. I know some of you will think I am messing my trunk up by mounting a camaro spoiler on it in the first place but I am hoping you will forgive me long enough to help me with this. Thanks, David
