I have to disagree with you - at least as a global statement.  My '77 B 
has a drive dog on the distributor that prevents it from being installed 
any way except for one.  It is a double keyed affair, where one key is 
sized larger than the other.  This does nothing to ensure that the 
stator is positioned correctly relative to the rotor, but there is only 
one way to connect the rotor to the drive.  What the story is on earlier 
years on MGB - that I can't address.
