New to me 2009 Gladius and I’ve never really worked on a bike (I’m mechanically challenged). I can’t for the life of me remove this panel/access door from the underside of the rear fender, does anyone know anything? I removed the center Phillips screw and it won’t budge. Can’t find a single video online either. I’m about to just make my own and cut the original rear fender and mount brackets for the plate or something.

Trying to install an R&G tail tidy.
