By that time, the "cheese cutter" IFF was long gone. I would have thought that this aircraft would have the dipole IIF antenna under the starboard wing.
The next work will be to install exhausts and engine hood before the assembly wings/fuselage and I think this step will be "sporty" => sand to get the correct fit, paying attention to the dihedral...!!!
and put wedges in the fuselage to correct the gap (or maybe some putty)
