As a long shot try James T. Parker in Somerset PA. He was my dealer growing up now defunct. Has a website and still NOS parts in stock. He probably still has my 73 H-1 that my dad refused to store when I moved away. Said he didn't want it but he is probably making a few bucks parting it out now...

Unfortunately a sleeve from a B3/C3 model won't work as those models used bushings rather than needle bearings.
