What does the whole mechanism look like? Anyone have a pic of one intact?
Bottom line would make one. It appears to be aluminum
. Would get a big chunk of aluminum or a hard plastic (delrin) an cut it to fit the hinge etc. if you want it to work
similar to original.
Or you could make a different one where it is a plate w/a tab cut to fit into the mast track to stop the slugs from falling out. Did this on a older Irwin
and held it in place w/machine screws tapped into mast. In most cases you remove it to put on/remove the sail a couple of times a year, so not big deal to get out the screw driver to remove the plate.
