Damn your old, just kidding. As a younger fart pushing 60, I too am hesitant on doing some stuff on my own, hell installing a FENFAB intake was my limit. Find a whipper snapper to do it for you, I'm sure you can find someone in your area to help. The sounds the trim makes when removing it is a little disconcerting, but it'll give way eventually, trust me fingers on the outside edges, pull down briskly in one movement.
