QUESTION: Yes. I suspect the original coil is internally grounded. Will I have to run a new wire from the positive terminal to a ground point ?

Answer
This was an attempt at a theft proof ignition system. The coil mounts to a bracket and a shielded tube runs to the ignition switch from behind the dash. it is a two primary coil pure and simple. A conventional two terminal coil can be adapted. The connection on the original coil that is on the engine side runs to the points and because the system is a POS ground the terminal that runs to the points would be + on the replacement coil.
