Pete,

Well the bushing is a bit thicker than the original fingers so the clamp 
goes on the bushing a bit tight, but I put the knob on tonight and it 
feels fine. I'll keep turning it every day and see how it holds up until 
it breaks or I get bored. Both my RXs are pretty smooth on the KC 
change.  I should probably put it on the MC shaft.  The clamp tightens 
down just fine.  If the epoxy doesn't hold up, I can always go back in 
and try the Locktite super glue.  The fit of the bushing in the casting 
was a loose sliding fit, being drilled by hand it was tighter at the 
bottom than at the top.  If it were 'reamed' I'm sure there could be a 
very close fit, but it would have to be machine done.  I think it's an 
acceptable fix for the price and done at home.  Right now it feels like 
it's going to hold up.
