The main obstacle and goal I think he wants to figure out is how he is going to mount the bar if he builds one. He wants to use factory holes, and we know there are the ones for the roof rack, and he couldn't find any in front of those mounts, so he wants to see if there is a way he could build one (unsure of revised look, could be just like the taco ones posted or something more similar to the FJ setup), so that it mounts into factory holes, because obviously drilling into part of the top of the windshield mounts would be an electrical and structural hazard.
I've thought about mounting the LED Bar to the roof rack rails. But I worried about the sunroof opening and closing.
