I have had the same noise in my 73 bus for years. I could swap it for a good 
used one but, since it's not got noticably worse in that time and I've been 
assured it'll last forever and not to worry about it, I'll run it to death 
first. Then again, if yours *does* self-destruct, secondhand synchro 
transmissions aren't that easy to come by.
