nwbasscat,BCB can confirm, but when installed at the factory, believe they use epoxy or the same type adhesive used in windshields. Makes it semi-permanent, but can be removed later by using wood shims to pry up. I previously installed same in previous boat and it was rock solid. Have seen others use velcro, silicone or other lesser adhesives. I have an Eyra now…and believe you have plenty of room to use short #2 screws in the location you are talking about, but I would confirm location with BCB first. Good luck.
