[Healeys] Throw out bearing

[Oudesluys]

The wear on the "fingers"of the clutch cover is no problem. Nearly all 
cars having a roller/ball clutch release bearing are of this this 
construction. It is slight and when they have gone to far the rest of 
the part is worn as well. Anyway, considerable wear on the clutch cover 
fingers indicates to little clearance and proper adjustment of the 
clutch is at hand.
