Aw man that is every pinheads nightmare .Glad you are sorted for a replacement !
I once went to pick up a Zaccaria Combat locally . As I was chatting and looking at another game , for some reason the young guy selling it removed the single backbox bolt - the rear panel was missing so he could access it without removing the glass - the backbox crashed onto the cab, backglass in a million pieces
Proper backglasses are beautiful things but everytime you have to remove one is russian roulette ..... I am so ridiculously over cautious around my Skateball glass
I remember being sad when my Earthshaker went ...then I realised I didn't have to worry about that backglass anymore
