We are using Marquez door panels. To make them work with the dash, we are making fiberglass pockets in the fronts. Its tough to explain, but the center pocket will be ended after the dash, so it doesnt colide with it, and the arm rest will flow down out of the dash.
In the rear, the panels are split around the roll bar and will have a double stitch seam there to match the rest of the upholstery.
