Yes, actually the plastic gear distributor has been superseded with an 
updated metal gear one, because of this problem.  Manufacturers have always 
made mistakes.  I remember when I rebuilt my first small block chevy and 
found that the cam gear had nylon sprockets (quieter) at the expense of 
longevity.  There were only about five of the 20-30 that were supposed to be 
there!  Needless to say, I replaced that with an all metal one.  I have heard 
of some instances where the 3B motors have -double-sparked, destroying the 
motor (hence the updated piece).  Not sure about the P/N, as it was already 
replaced when I bought my car.

'91 200 with a few mods...
