[Mgs] Hot clutch shudder

I had a similar problem on my 66 MGB.  The clutch would shudder only when it 
was hot, after sitting in traffic, etc.  When I pulled the engine and 
transmission for a rebuild I discovered the throw out bearing was totally 
shot.  There was no oil contamination. The clutch disk was dry and in good 
shape.   I did replace the entire clutch during the rebuild and the problem 
is gone, but the only thing I could see that was bad with the original 
clutch was the throwout bearing.
