I took it apart I think i can get a glass place or use some of the special plexi glass like lexan to fix it, But with the replacements about $50.00 for a set off ebay, I may just replace them both..
I placed a piece of fireplace grill type mesh over my girlfreinds 2000 Mazda Tribute fogs, she's broke a few before I did the mod. It worked, I think they are close to the Gen 1's fogs.
