KF5 turtle deck/antenna install

[SilverFox5]

Hello,
Looking for help from anyone that has built their own Kitfox 5.
I am trying get everything done on the fuselage to get it ready for fabric covering. (Using Oratex). I'm confused at the instructions concerning the turtle deck and antenna plate install. The manual does not have you do this until after final assembly after you have the the complete windshield assy installed. But from pictures I see it looks like the antenna plate area needs to covered with fabric. I would like to know how others have handled this area. If i mount the rear cross bracket for the turtle deck before covering, will that mess me up later? These instructions are in the kf5 manual in Chapter X, Page 65 and 108.
See pictures attached.
Thanks
