A few years ago I was going to build a Power Products engine for my Rupp Dart cycle I bought this NOS 9/16" clutch assembly from Power Products guru Hank Rotoff...or he told me where to buy it I forget which. I ended up building a Lauson 4 cycle for it.
Anyway it is sometimes hard to find the 9/16" bore...just need the Noram drum for it I think is 3-1/2" (3-3/8" I.D.). You can also buy different springs for it to adjust the engagement speed.
Might fit a Westbend 580 and others but check your application...
Cheap date at $22 shipped.
