what wings? Those are tiny little stubs for carrying external fuel tanks
The reality is that this plane was designed as an interceptor for long range bombers and never intended to dog fight, so really it only needed lift at low speed such as take off and landing. At Mach 2, there is enough lift just from the fuselage. Since the wings were so thin, they held no internal fuel at all.
So here it is:
Internal frames
dry fit the frames to the mating stub spar on the fuselage
the small stub on the wing bottom is to align and glue to the wing pylons.
Now add the wing skins
and glue to the fuselage.
These have been the easiest wing build ever.
