320-01. The blade disc is a nice tight fit, but I'm not sure what sort of boss these had originally. Any ideas on this? Did it even have a boss? The fact that it is such a short shaft and came to me with just 2 washers and a nyloc nut on the shaft, suggests to me that this might have been all it ever had?
Still have wheels to repair on mine. Gradually building up with glue and filler.
