i cant do it any other way dude. if i did go this route id take my headliner out and make sure the holes are sealed
up to you man. be sure to put some good size bolts/ washers on it. the roof is kinda thin. little self tapping screws would either strip out and get ripped off, or it would dent the roof. I dont konw how you drive..but me.... it would get ripped off haha (hit dirt roads, speed bumps, small childeren....etc)
haha yea i was thinking about that. ill have to see how it calls to get mounted on and adjust it accordingly
