Nothing out theer as of yet for side mirror mounts but there is a little do-hickey for a wranger hood that can be used on the front bumper of the KK and can hold to lights

I personally would love to see a side mirror mount. If I were to take a swing at fabing up something, I would look at mounting on or near the joint where the mirror swings inward. Maybe like a bracket that could fit over the center post in that hinge. Maybe even at the very rear corner of the hood
