Help for an old Howard tiller

[ColdRider]

I have had this tiller for years and can't find parts. The only numbers are on a plate; 812 B50 under this is ?735. The slip clutch is worn out, one friction plate is completely gone. I would replace the whole clutch if I could find one. It is 5" in diameter and all I can find are 6 and up. I don't have any extra space to go bigger, it would hit the mounting plate for the gear box housing. The shaft is standard 1 3/8 splined. I want a new pto shaft too, but that is buildable. Any help would be greatly appreciated. It is to good a tiller to not repair it. If all else fails I'll shear pin it.
