Decided to install the gussets to the canopy support frames. Separated the F-01245A into left and right gussets and deburred the edges. Match-drilled the holes in the F-1254 Support Frames and F-1234 Canopy Decks. Final-drilled the top holes in the F-01254A Supports/Gussets. I messed up the holes in the right support. Will get a replacement part from Van's
