Been working on the rear wheel this week. I'm not sure what the rear hub is but it looks similar to an early conventional Yamaha or maybe a front hub from a Kawasaki Mach lll ? I don't have a disk or sprocket, but the sprocket is easy enough to replace. Anyhow, a new disk was sourced that should be just the job with a skim down...from an early Triumph Spitfire or Herald car !
