The pivot points on my 2002 Motorguide Gator mount on my 02 P3 have gotten worn and it makes a lot of noise when hitting power. So Im going to buy a new mounting bracket. Wondering how much trouble I might expect when pulling the hold down screws from the old one. Are they just screws or will there be backing nuts inside? Assuming screws, am I right thinking theyll have lock-tight on them? So wondering if I can expect to need to use an impact driver to free them and if there are any tricks for doing that to avoid any problems. Thanks!
