heres a drawing of the centerlink pin & bushing using lineform
the gold-colored, outlined graphics are the nylon bushings to be replaced with bronze...the best/worst part about it is that the stack of washers for the gap between the arm & link (the 0.4625" dimension) will need to be sized according to the taper of the pin...this basically means getting an assortment and sitting down with a dremel for a few hours and carefully grinding their IDs to match the taper, one at a time, so they're nice and tight...crap.
