Part needed, Ballast Resistor?

["R L" <super70ty@xxxxxxxxxxx>]

Hey all,
I am trying to get my 1977 Hornet Sportabout running and while playing with 
it, we noticed that the ballast resistor(?) had the wire break off of it. 
This is the cycilnder shaped part the bolts to the  ignition coil and 
connects to the wiring harness. Is that the correct term ballast resistor? I 
am having a hardtime finding the part locally. Anyone know where I can find 
one?
Thanks
Ryan
