I'm new here and have a small question concerning the installation of a front spoiler on my 73 Convertible.I've talked to a few people but they couldn't help me,looked at a few pics also( that didn't help much either), the locations of the spoiler(s) all seem a little different in relation to the fenders( the very ends near the wheels). Does anyone know of any industry standards as far as measurements go, or would a good body shop know, any help would be appreciated, it's just the basic black plastic.Thanks
