Brief Description: Rivet arched rib together with splice 2
I made sure I had the rib in the right position, by putting the canopy back on adjusting the rib to fit and then putting in a bunch of clecos and the 4 #3 bolts. This helped hold the position.
Then I riveted it. I checked fit after a couple of rivets just to make sure it didn't shift. They call this whole canopy assembly the 'shape shifter" for a reason. I already saw it shift shapes when I riveted the splice plate that holds the side rails onto the front frame.
