I found the following tapered roller bearings in timken catalog and for sale on line at numerous places. they come close to replacing stock ball bearing.Might need alittle sanding on spindle.
outer repalcement
timken 1975 and 1922 parts
inner repalcement
timken 3387 and 3339.
Look those up and tell me if you see any real problems using these. I would appreciate any feedback.
one website cost per side is around 65 dollars.
