Loose raw plugs

Hey all, I've got two loose raw plugs on the high end side of my neck pickup on my Warwick Corvette Std. As it is, I can't lower the pickup because the plugs at as the anchor for the pickup. I was thinking that super/wood glue and a hammer would be the way to go about dealing with this but I'd like to get other opinions before I go much further. Thoughts?

 

If you open up a Warwick corvette (not sure about other models) pickup cavity, you'll see little brass rings where the screws for the pickups anchor down (beside the springs). Those are called raw plugs, mine were loose. At any rate, surgery was a success! All is now well in Warwickville.

 

Yes, those.
