How to replace the catalytic converter heat shield on Buick LeSabre?

Replacing the Catalytic Converter heat shield is such that you must remove the exhaust system while making sure there is eye protection on to prevent injuries when drilling together the rivets. Drill the center of heat shield rivets, pull down on heat shield to help it break free from keeping stud and slide to left under oxygen sensor wiring harness heat shield. When installing, place the heat shield by sliding it to the right under the oxygen sensor wiring harness heat shield, slide upward over retaining stud, align on the floor panel hole in heat shield so that it's in line with the hole in the floor panel. This necessitates the use of a rivet gun to secure both the oxygen sensor wiring harness heat shield and Catalytic Converter heat shield to the floor panel with single rivet and securing all the remaining rivets before the reinstallation of the exhaust system.
