I planned on putting in the front seat so I could actually sit in the airplane and figure out the switch layouts, etc. For some reason I never riveted the hinge that holds the seat bottom to the floor board. I did this real quick - it was nice to use the rivet gun again. Anyway, I installed the floor boards in the front and the seat ramps along with the front seatback. I also installed the instrument panel - I must have sat there in the airplane for 30 minutes just marveling over the view - too cool! I also primed the comm antenna doubler after I c/s the nutplate rivet screws.
