Wanted Wildgame Innovations game camera needed for parts

[Mortigan]

Anyone got one that's broken or they hate?  I just want to remove the round glass that covers the LED array and use it to fix another unit - they don't offer ANY replacement parts!  The model is the N8D but that glass piece is common to most of their cameras.

 

Barring that, any idea where you can just buy a two inch diameter piece of glass (of a specific thickness) to drop in the hole?
