Hello Cinan, you will need a suitable thickness packing washer without the locking slots to take up the shaft gap for the large nut when tightening back up.
also, if you go this way I would pay a few sheckles for the locking washer and the dished washer for the nut if you no longer need them.
I was lucky enough to score a brand new lunette and mounting module. However, it came without the nut and washers (2)
I've got the nut so far and that's it. Would like to make it a locking lunette.
Message me if you (or anyone else) have these washers spare thanks.
Greg Mac.
