So removing the small PK screws that hold the covering to the Ribs is tough. They are an unusually small Phillips size. I tried a #1 but it would slip out easily. Someone on FB recommended “Vampliers” which are a specialty set of pliers that are srpingloaded open and designed to grip Screws!
Well I can tell you, a couple of turns with the Vampliers and those screws came right out. Great investment to my Toolbox for about $25 and ordered from Amazon. See the video below.
