Tonight I went to a local vendor to get some more pachislo tokens. He had a pachinko machine too. It is by Sankyo and was some wierd YMCA music theme. Any way I noticed this machine was MUCH more quiet then my Godzilla. When I say quiet I mean the balls where barely making much noise from hitting the glass. There was no clanking sounds like I get.

So I checked the machine out a bit and found out the window is double paned with two sheets of plastic. Probably lexan.

When I came home I popped open the window door on my Godzilla and realized I only have 1 pane installed. The one closest to the play field and that mine is made from real glass.

So, this is the cause of my clanking. Question is where can I get plastic windows for my machine? Is this a part I can order from someone?

I measured the current glass piece in there and it is 15-15/16 square by about 3/32 thick.
