Have been searching the forum and google for pictures of conduit but not seeing many results of how you are punching it through the uprights for the center section if you are running it along the sides of the plane. Are you terminating conduit and running wires straight through the couple of bushings they had you insert early on in the fuse build up or drilling 7/8 inch holes through the uprights and is vans ok with drilling these without extra support?
