Nice start to your build.
I have a couple of OEM parts (well fiberglass copies if you are interested).
I have the moveable "batwings" left and right sides and both sides of the coupe version of the filler panel between the moveable batwing and roof. I can post photos if interested.
FYI, would you be willing to pull a mold of the transition area where the roof wraps around to the side? Its the area between the roof and the door/rear side glass. My roof section did not have this area done properly. Also is that fuel tank any good?
