My shower door fell off! It is a corner shower where the door swings out from the two side panels. It has a metal frame. The door was held in place by a top and bottom small L-shaped piece that is screwed into a a long hinge (like a piano hinge?). The top L-piece is gone (looks like the screw was stripped) and I can't seem to find a replacement. Neither the local hardware store or Home Depot carries such a piece. A local glass place that sells and installs shower doors indicated that I would have a difficult time finding such a piece. I really don't want to have to replace the whole glass shower at this time! Any suggestions on where to find my missing piece (and yes I looked all over the bathroom for it!). I've searched some internet sites, but can't seem to find the right thing. Thanks!
