Hey John I looked at the tractor and the shaft is too weathered to tell what was on it and I had another guy tear it down years ago so I never saw it to know which style it had. There are some bushing types on ebay every now and then but I have seen two different thicknesses,and since the bolts are gone also I'm just shooting in the dark. I saw in my Oliver shop manual that they can be converted to the bearing type. How big a job is that? Thanks again
