IMHO, don't deal with glass if you don't have to.
Measure the width of the glass (or where the glass should be) at the widest point, then the height at the highest point.
Then go to a local glass shop with those dimensions and get yourself a rectangular piece of 1/4" polycarbonate... Lexan MR-10 or Makrolon AR (depending on who they're a dealer for)
Take that rectangular piece home and cut it to your shape with a jig saw with a medium-fine tooth blade (and go slow). Polycarbonate can be cut, drilled, edges sanded, etc with no need for special tools. There should be a peel-coat on both sides... leave that on until JUST before you're ready to install, or if you're good with the razor knife, leave it on until AFTER you're done installing.
