Our catalog record ties this specifically to the front wheel group, appearing in both the disc-type and drum-type brake figures for 1973. That means it was used across more than one front wheel configuration that year, though we don't have detail beyond that on exact model fitment.
If you're chasing a wheel balance issue on a Norton front end, this is a small, plain piece of hardware worth having a few of on the shelf, since it's easy to lose track of how many you need until you're doing the job.
