I'm using the thick lock nut I removed from the innards as a stopgap, obviously not a long-term solution (not least because it needs a 17mm spanner).
Vintage British motorcycle suppliers seem to have plenty, I've ordered a baggie to be on the safe side.
^ these duly arrived, and they fit more precisely on the axle than the Shimano 'acorn' nuts. So be safe and make sure you have the correct nut for your axle when fitting a hitch bracket (I for one never realised there was such a variety) - other nuts may
feel like they fit, but they don't grip...
