John, One minor thing I forgot to mention which can be very important later. When you remove your active wing assembly, it may require just a bit of pry to pop it loose from the hatch after you remove all the nuts fromt he underside. Strong fingers or a plastic tool will do the trick. The reason is there is a gasket of sort to keep water from getting into the hatch. It is just a rubberized self adhesive weather stripping, pressed down when the panel is bolted in place. Any hardware store should carry it. If not available, a bead a silicone should work just as good. But don't over do it, as it may be trouble to get apart one day.

Good luck with your project. James
