Need EXACT location for mounting 3rd Gen spoiler please

[AKcharger]

Got my new Gull Wing today and ready to install, but before I put a drill to my car need to know where EXACTLY it goes, any help/photos greatly appreciated 

Thanks in advance!

The exact placement is determined by the cut-outs in the deck lid inner panel.  A few early '72s had them, but I assume yours didn't. If nobody chimes in with the exact location, I can take a few pics of the cut-outs on my extra '71 deck lid (My Rallye doesn't have them and the Bee has the spoiler mounted).  In the mean time, this might help.  It's from an original engineering drawing in 1970 for 71-72 B-Bodies. The view on the right shows body grid locations. The 18" from center line is obvious, the fore/aft dimension probably won't help much.

I love your car, by the way

If it does not have the cutouts as mine did not I used this from YO and a little ingenuity.

Also, I did not want the outer skin and inner skin to collapse together when I was tightening the mounting studs. I drilled the holes exactly where the diagram measured. The underside skin hole I reamed out bigger that the outer skin. This enabled me to slide a nylon spacer over the stud and just inside the inner skin. I place a larger washer over the stud and tightend the nut. The nylon spacer allowed the wing to tighten up and prevented the outer and inner skin from collapsing. I place a very small amount of silicone on the base mounts to prevent any water leaks.
This all worked for me. Look at the pic of mine at the bottom.

Always measure 10 times and drill once.

I forget if the firstplace auto Products spoiler came with the instruction set or I got it of the 71-74 Charger site.  I am on the rig offshore now so I can't hunt for it. I think I got it from the 71-74 charger site.  Here is some pics of mine if it helps.

Actually that helps a lot, Thanks Beer!
