Brief Description: F-706 Bulkhead - Notch Rib Flange for Rivet
I noticed on my brother's website that he discovered an interference between rib flange and rivet heads when it comes to installing the forward floor beams. So I put in some rivets, marked the interfering material in red ink and sanded it off using the Dremel sanding drum. I had to do both ribs and the plate. Looks okay. I have second hand info that Van's approves this method to make clearance for the rivets.
