My '69 Chevelle/Winston cup car

This will be the quarter window treatment.(searched high and low for that solution) so the front windows will still operate and seal properly. Made from Lexan, they will not roll down on either side. I havnt decided yet but the drivers side will have a Naca duct like in the pic for the rearend cooler for sure and I might double up the drivers side and add one on the pass side to route cool air to the rear brakes. Ditching the glass window and crank mechanism saves 16lbs per side! I weighed it.
