Not a great shot, the hole on top of stabilator for shoulder screw is not cleaned up but is a machined piece that allows proper seal for shoulder screw. Notice 2 seals on screw, guess you can't easily tell but there are 2. No drain needed. The top of screw is perfect flush with stabilator and need a allen wrench to remove. In the very unlikely chance that at the same time the 2 seals ever got loose, we have a small Delrin round nosed plunger that falls into groove on shoulder screw. Figure if ya r gonna do it, do it right. Since on the subject of ball plungers, I added one to the T Bar to keep viabration from banging it back and fourth, holds things nice. Sorry no pic. Green is glass/Redux that is holding foam and recess in place.
