I just drilled the holes for my gills a couple of days ago! I wanted my gills to fit
flat against the quarter panel. If you notice the gills have to fit into the indentation
of the quarter panel exactly. My holes were dead on, but what happens if you were
to hold the gill in your hand and look at it, the 3 pieces on the gill is at an angle
that will not match up well with the curve of the quarter panel. Put one of your gills
in the holes and look at it from the top down, You'll notice that its sticking out from
the quarter panel even when it seeded down in the indentation and tightened down with the nuts. So that's where I modified the gill, if your brave, take a grinder to nock down the angle of the gill in the corners, on the top and bottom. I know its sounds crazy, but my gills fit flat against the quarter. I started with a flat file, but ended up using the grinder. Its a big risk, but then your only out $80 if you f-up! and Im taking the black
off the gill and making them all chrome. They spray the black right over the chrome,
so the black comes off easy!
