The seals and one crank bearing is still available OEM. The other bearing is NLA and is kind of a bastard to find. I have a couple case's here and I can listen to the bearing's if you are interested in the whole case.
Thanks for the info I'll check into when I get a spare minute. Right now I'm in the middle of beating my head against the wall for not hearing the sowed bearings before I shelled out the cash I did lol. O well its worth fixin
I did see the seller you mentioned did have one seal on his ebay page, assuming that's the proprietary seal. I may get that one and have that part at least
