So, these F-684’s require that they be trimmed and bent. It’s one of those trim/bend trial fit, repeat sort of things. I decided to make it a bit easier by removing the firewall. But the location of the gusset depends on the F-713 Auxiliary Longeron. So, clecoed on the F-713 and then put a cleco clamp flush underneath it. I can now take off the 713 and the gusset will rest on the clamp and be in proper up/down position.
