There really aren't seals for the wing "feet" bit there are o-rings on the studs. My o-rings looked really good, so I reused them. The bottom of the feet have a metal insert in them that rusts, so I coated them with some spray lubricant / water repellant like WD-40 to try to keep moisture off of them. I also put a bead of the caulking rope (a very thin bead) in the bottom of the foot well to prevent moisture from getting in there. If you end up needing new o-rings, I'm sure an auto parts store would carry them. I think 180 listed the size of them somewhere on the forum.
