I can comment, and I think Interceptor 398 would confirm, even when new there is a little more clearance between the spindle and bushings than you might expect. Also a source of slop for me was in the spindle to ski saddle connection. Again even in new condition, the clearance is a bit more than you would expect. I think the only way to really tighten it up would be to turn some oillite bearing stock to make new bushings for the spindle to bulkhead and spindle to ski saddle which are a couple thou less on the ID.
