Didn't have a warm body to help bleed brakes so decided to fab in the centering bolts that will keep exhaust tips centered in the valance. Due to accessibility I put put 2 bolts near the bottom, and 1 bolt through the top that will be adjustable through a 3/8" hole in the trunk floor with a body plug. The original valance work was done using 1/8" pieces of steel tacked to tips to center seen in the pic showing exhaust tips on.
