Quoted from Scrimmbo:

Yesterday I was buttoning up a Nascar pinball at work, I had done some work to the driver board and had just put it all back together. So I put the backglass in and carry on with some other stuff at work, about 15 minutes later I walk by and hear this crackling noise. My first thought was that it sounded like something was arcing, so I rush back and see that the backglass is completely spider webbed! Luckily I had a few minutes to get ready for it to pop, and the mess wasn't too bad (thank god the playfield glass was in!).
Now I'm hunting for a replacement, Marco has them listed but they aren't in stock. I talked to a local glass company we work with and they can get the glass but it's going to be way more expensive than what it was listed for at Marco. I searched around here for a bit, and didn't find much, so I figured I'd ask you all if you have a go to for this sort of thing!
