I have a few older Mallory parts that I would like to identify; maybe someone here can help me. I have two points sets p/n 100. I think they're used either on the dual point conversion kit or they may be early GM V8 replacement points. I also have an ignition coil p/n 28675. I believe that this coil is a standard 12 volt negative ground ignition coil to be used with a points distributor and ballast resistor. Can anyone tell me if I'm correct on that? Thank you.
