The bushings you are speaking of have a fair amount of play even when "new"... I've already run into this... Kawhead might have new bushings? I don't have any... I get split bushings made through my machinist with a tighter tolerance. Even though the bushings are designed to wear faster than the shaft itself, there is always a little shaft wear over 30+ years of use which is why even new bushings aren't a perfect fit. Obviously better than the old, worn ones though. Check ebay if you can't find any through here.
