Call me lazy, but I have removed/preserved/stored safely away all 12 of my tub's fidgety dzus fasteners, found some plastic plugs of the correct size, used a dab of silicone adhesive on them to cover the holes, then added a couple of strategically placed drawer pulls to make removing/replacing the tub quicker/easier/less painful.
Your mileage and/or adhesion to strictly stock may vary............
