Trimmed and shaped all four center seat ribs. The two center ones are removable and the other two are already riveted in place. They all came out with about the same radius and are now all smoothed out. There is about a 1/4 inch clearence on all of them in the full up as of now. I may need to remove more after I trim the spar plate.
Drilled along the lines and used dremel to finish.
Once cut I used the air grinder to smooth these out!
All smoothed and test fit, these ones were a bit harder as they are installed!
