Mandrel cups for old Sears tractor

[BrianinMichigan]

I have been looking for new mandrel cups for my Sears tractor. It dates back to the early "70's". Sears no longer has the parts. I was wondering if anyone knows of a substitute part for this? The diameter it has to go over is 2" the shaft size is 3/4" I have got to believe that there is something out there that still uses a part like this.

Well I finally found them and I think I bought the rest they had. The guy I talked to said they had been sitting on the shelf since 2005. Mower should be up and running by the end of the week.
