Sorry to hear about that. I myself had a XLG BGE that I took apart to pressure wash every year. then one years with the help of my wife as we were putting the top back on I thought I had it under control and told her thank you I got it from here. The hinge wasn't seating as perfectly as I had hoped on the New gasket so I loosened up the ring to re-adjust it and the damn thing slipped right out and smashed itself all over the ground.
So I have been there my friend. Not a happy place to be. Sorry for your loss.
