[Healeys] Throttle Bushes

... and another on the gas pedal shaft--4 total--although that one 
doesn't suffer as much abuse (that was the 'under the dash' part).  
Can't speak to your car, Bruce; the instructions show these are suitable 
for BN7s.  Maybe prior to BJ8s they used something different (can't 
imagine cork would hold up long at all).  Mine were rubber/bronze 
bushings in a metal cup; the nylon/teflon ones still go inside the metal 
cup.   Looking at Bruce's photo, you can see the ends of the cup 
protruding from either side of the brackets, although I don't see any of 
the white nylon bushes.

Every time I think I've done every possible job on a Healey it proves me 


ps.  Of course, it's Eric GruNden, not Gruden.  Guess I still had a 
little football in my head.
