I was going to suggest what DIck2 did. Boring the old hub for an insert might be an option.
In my neighborhood, American Implement in Mount Calvary, WI might have something.
Worthington Ag parts got me some 105 parts last year... I call somewhere in Iowa, I think Iowa City. Their parts systems didn't function via JD's numbers anymore... but I emailed a picture of what I wanted, and came up with something.
It may be helpful to know in advance if that same hub is used on, say, a 55.
Good Luck and I hope you get her going again.
