John,
Where I attached the shields is about half way down the the inside of the rear quarter, on the inside of the car about 12 inches up from the floor of the rear seats. In my case, once I put in the rear inside side panels on either side of the rear seat, I won't be able to get to the shields without again removing the seat and the side panels. What you seem to be saying is that I have them in the wrong location, and they should be up at the top of the inside sheet metal of the opening where the quarter window glass comes out when cranked up? I'm at home now and the car is at the shop until Monday morning or I'd run out and have a look at your suggested mounting location. I'll check on Monday and take the camera with me. I'm under the gun here as I think the car goes back to the customer on Friday, to get an exhaust and top put on.
