When I R&R'd mine last year it was in bad shape. The bushing had
ofcourse frozen solid in it's bore. It was then subjected to wear from
the bolt, which had also loosened up making it even worse.
My solution was to put the bushing in the lathe and bore it out to
accept a new larger bolt. I suppose I could have sourced a new bushing
and bolt, but that would have been too easy.
