Does anyone have a photo (or template) of the cut out section of the rear valance on a '69 or '70? I am doing some work on a friend's GT500, which has no rear valance on it at this time. Thanks
OK going off of the centre of the valence. The screw hole between the two plate insert square holes. 1. Measure 1" down. Make mark. 2. Measure 6" each side of mark. 3. Measure 5 3/4" down from the marks you just made. 4. Connect the dots and you should cut out a rectangle 5 3/4 X 12". 5. The rectangle will be in the centre of the valence 1" down from the middle screw which holds the valence to the car.
If there is no valence on it now, I think you can purchase those with the holes already in them. Tommy
