Finished assembling the center section. This involved adding the center seat belt lug with spacers. It was really stubborn about fitting so I ended up having to drill the seatbelt lug bolt holes 1/64th oversize.
Then got the spacers drilled and installed. Finally got the nut places mounted and the flanges riveted together. I accidently added two rivets I was supposed to leave open so I had to drill them out but all okay.
I left the holes called for open but I wish there were better plans for the optional rear rudder pedals. I have a feeling I'm going to end up drilling back into the webbing here in the future when this has been installed. Would be easier to do it now.
