I wonder though, how many times those incidents include other upgrades to the 
ignition system, like Lucas Sports coils.  The rotor has to withstand any 
increase in voltage, and the path from the contact arm to the distributor post 
isn't very long at all.

Caravanning home from VTR 2000, a local club member had a new rotor (installed 
@ VTR) fail on his TR4A.  Failure itself was invisible, a carbon track through 
the interior of the rotor, grounding the spark to the dizzy shaft.  He had a 
Lucas Sports coil, and, as it turned out, a bad spark plug connector that 
evidently allowed the coil to develop more voltage.
