Attached Seat Pans and Baggage Floors

I didn't have much time to work on the plane today, but I wanted to get the center section flipped over and put the seat pans and baggage floors in place.  The baggage floors and rear seat pans lined up easily, but the forward seat pans (the ones with the large holes near the front spar for the control sticks) are having issue.  I started fluting the seat ribs near the front end which seems to be helping significantly.  I still have some tweaking to do before these fit nicely, but it's late and I'm beat.
