I just bought a Squier CV Jazz, and I want to install a chrome pickup cover, because I like using them as a thumb rest (also, they look cool

). My problem is that the routing runs right under where the bottom screw would go.
I feel like this might cause a problem with the bottom screw not having enough material to grab on to, and I was wondering if there might be a threaded insert I could use rather than just running a wood screw into the pick guard and hoping for the best.
Also, if I was to keep the cover off for any length of time, I think the inserts would look a lot cleaner that just having two gaping holes there, so I'm really hoping this idea is viable.
So anybody tried this? Have any tips on installation? Recommendations on what hardware to use? Any help is appreciated!
