The canopy track stop was put together with drilling another hole in the vertical side for a screw. The original hole was too close to the attaching screw hole, so another hole was drilled. I screwed up and drilled the second hole with a too-large a drill bit for a #4-40 screw. I drilled a third hole with the proper size bit and then tapped the hole. The spring was cut to a shorter length, so the spring offers resistance and pulls the stop lever back into position. The track stop was then installed onto the right rear pin mount.
