The top rib was added to the passenger seat partition, completing this area. Also, the original antenna location is not really compatible with the safari windows that are being added since the passenger side windshield would swing into the back of the antenna. The factory got around this problem by having a special antenna that was S-shaped at the bottom for clearance. I could probably fabricate something close to this special antenna but since I think that looks weird I’m opting to instead fill the hole. I’ll worry about the antenna later, there’s so much glass surface area that I may be able to mount it hidden under the headliner and still have plenty of reception.
