Fantasea- UWL-09-Hood attach help

So... just getting everything ready for my next trip and sale. For the life of me, I can't re-attach the hood.  There are 4 tiny screws, and a 4 piece gasket. When I called the shop of choice, the instructions were very vague and not super helpful.  Not anything on Youtube or in the manual. I figured someone here would have the answers, any help would be appreciated.

Thanks to Gary Haas of Haas Photography for reaching and setting me on the right path for this.  Great knowledge, great conversation.
