I used the C-frame to back rivet the hinges onto the left side floor. Cleco'd the floor in and made the hinge pins for the seat back to floor. Had some difficulty inserting the pins so I tapered the end of the pins and applied some Boelube. This made the pin insertion much easier. Removed the right side pins and gave them the same treatment. With both seats installed I got some cushions from a patio chair and tried out the seats for comfort. Very nice!
