Thanks looking at my photos I do wonder if my half nut has been trimmed down to fit that plate, I will get it out later and have a good look and send a picI'll take a photo when I dig them out, including one of the half nut so that you know what that should look like, as there's a chance they may have cut the bottom off yours.
Thats what I was hoping.Aye, you could join the pin from another half nut. If that existing pin is long enough, you could also just shape, (if necessary), and notch that.
