I was watching Greg Halligan's rebuild of his 13" South Bend, and in his episode of rebuilding the headstock, he showed that he replaced the fiber washer with a needle bearing/washer setup from McMaster-Carr.

I don't have my headstock apart just yet, but I was able to take a measurement of the OD of the rear of the spindle, behind the gear, with a micrometer. It came out to 1.437". The closest needle thrust bearing and washer McMaster has is for a 1.50" shaft. Or is the shaft thicker at that spot?
 
I replaced mine with an Allison transmission thrust bearing Mine is a later model (1966 CL145) and had roller ball thrust bearings so I don't know if these will work with yours. They are considerably thinner than the stock bearings and I had to turn a shim washer for mine.

I'll take a look for those. But I think I might be OK with the ones from McMaster. I took the headstock apart today and the shaft on the opposite side of the collar is 1.50". It occurred to me, as I was taking it apart, that the non threaded piece would HAVE to be smaller in order to fit the threaded collar.
