Received the new 631-A canopy frame bracing from Van's. I was able to install these with a 1/4" gap and they looked good. It was a good idea to replace them. Drilled the connecting plate and riveted to one side of the 631. Also riveted the forward WD716 to the side rails with the predrilled 613 connecting angles. Removed the frame for deburring, dimpling and priming.
