Yes- H & R clutch is very good- have used them myself on occasion. Good luck
Yes, YALE was of no help, too old a lift.
I found a re-builder in PA that did some research, and
they determined that it is a 12 inch disc, but two possible
input shaft diameters.
They are sending two discs, one of each size, and I will send
back the 'wrong' one with my old core.
Price is reasonable.

Have you tried getting new clutch from an aftermarket source? I'm not sure anyone is going to have the information you need
