[Mg-t] Ignition coil

[Charles Hill]

If it is for a TD, no.  That is an unballasted coil.  It should be used 
with a ballast resistor.   I think some late-model MGBs used ballast 
resistors but I definitely am not an MGB expert.  The coil you would 
want will have a resistance of around 3 ohms across the primaries.  If 
you don't know about ballast resistors, ask any old MOPAR enthusiast and 
they will tell you more than you want to know.
