It's a vertical surface, yes? Is your track attached with both screws and nuts and bolts?
The bolts can just be tightened no? Probably a two person job. Someone inside with a wrench on the nut.
If the screws are loose and spinning, couldn't you just fill the hole with a little thickened epoxy with a syringe and redrill? Some clear cellophane tape or plastic wrap? should hold it until it sets.
