Bill, I am not pursuing the pin replacement. I have made the bearing acceptable by replacing the dowels and with judicious shimming under the rest felt in the tenor and bass. My final decision on the pin replacement, had I gone that route would have been to replace only the bass if needed where there is a heavy mass for the strain. Good point though and I'm glad I did not go gung-ho, full speed ahead. Thanks all, Jon Page PS I did find the two missing aloquats :-) hiding under a piano. whew.
