We're getting ready to cut into the fender patches to install air extractors for the '72 GTO. I can't find any diagrams or details on where these things go, so using some photos and measurements from an actual fender we did a little math and came up with the extrator to be mounted...
6.83 " above the bottom of the fender, parallel with the bottom of the fender.
3.56" back from the fender opening (measured at the lower corner of the extractor)
3.56" below the "point" in the fender, the sharp countour in the middle (measured from the upper corner of the extractor)

First we'll mock it up in a piece of metal to see if we can cut the hole and flange the metal properly. Then into the actual fender. Will let you know how it comes out.
