I see that on the newer models there is no center skylight rib. My model 5 manual calls for it but it's missing from my kit. I also have the shorter windshield so there is a connection between the windshield and the skylight. Curious to know if others have deleted the skylight rib all together or is this rib necessary for whatever reason on the older kits? I am leaning towards leaving it out since the connection strip between the windshield and the skylight is "V" shaped and does offer support, and the fact that the newer kits don't use it. Any thoughts......
