Last time I was under the hood I had to lift the fuse block a bit, which required loosening the bolts/nuts around the outside of the fuse box.

While I was in that area I checked the two screws/bolts that were in the center of the fuse block itself. They were loose, however it didn't seem like I could get them to actually tighten down, almost as if there wasmt enough thread engagement.

Any one else ran into this?
