Here's the firewall, sides and F-22 test fit:
Everything in place, used the plans method to squeeze the sides together, and used dry wall screws as well. Really didn't have too many gaps, test fitting everything on the jigs helped a lot and a bit of luck didn't hurt either. Only real gap I had to work with was on the bottom of the starboard side of the seat back.
Everything looking good and level.
Now to leave it alone for 24 hours
