Transferred the template to .025 sheet stock and cut out the cover using a dremel. Used a hole finder to locate and drill the 2 aft holes to #30. Used a brake to put a slight bend in the front end of the cover where it overlaps the control mount. Punched 4 holes with my Whitney Jr. punch, then match drilled the cover to the control mount. Used a fly cutter to cut the hole for the vent. Installed the vent to the cover, then installed the cover. Will need to add 4 nut plates to the control mount as well as a couple of nut plates at the rear of the cover. This somewhat simple mod seems to be taking way too much time.
