When I had my passenger seats off, a piece of broken glass accidentally fell in the bolt hole nearest the rear-passenger wheel. Any suggestions on getting it out? Should I just leave it there? I am worried that since glass is sharp, it may cut some stuff up in there....

 

Is the hole closed at the bottom? ... Shop vac. If you can't get enough airflow in the hole, drop a straw in it parralell to the vac nozzle to give incoming air a path.

 

I tried vacuuming but it's not strong enough to suck up the piece. I guess I am more concerned about it doing any damage to something. What do you guys think? It's a piece of glass from the shattered passenger's side window.

 

I took my driver's seat out a few days ago, and some of the holes are straight through. if the bolt it out, poke in there with a thin screwdriver, and if it feels soft, it's the undercoating. Don't worry, just put that seat in, bolt it in, drop yer girl in there, and go for a cruise.
