I can't see why those fenders will not work with that corner armor.
I have had those those Bushwacker fenders on my TJ for about three years. No cracks so far. Maybe the Texas heat keeps them from becoming too brittle? They came highly recommended from a friend that has had his for a few years. One of my brothers has them on his YJ.
We are ranchers and hunting outfitters. So, we drive through brush all the time. I did have a bull hook one of the rear fenders and pull the bolt heads through. Quickly fixed with washers. I guess your mileage may vary.
