Thanks Joe for your input plus all the others with your suggestions. Is
there any steel in the top-hat bushing ? I still wonder where the 2 steel
chunks came from. There is no unusual noise.
As for Randall's suggestion, I have a non-overdrive box I can put in. At
the moment it runs fine and I can wait to get it done next winter. I feel
it's not urgent. I was mainly thinking that it might be done by an expert
while I'm waiting around for 10 days.
