I don't think you have much to worry about, the rest of the ancillary 
electrics don't "care" if they are positive or negative ground, lights 
doesn't matter, heater blower motor doesn't matter,  wipers, blinkers ditto.

If you have a modern radio this will be an issue as it will be negative 
ground, if it has an original period radio probably positive, but worth 
checking (not sure how, unless it has a polarity switch or is marked on the 
outside somewhere).

The coil will work both ways, but better if the small "+"  "-" wires are 
hooked up right, if this is part of the motor with "generator everything" 
that has been set up positive earth you should be there too.

So the only thing you might blow up is your radio, if you don't have one you 
should be able to just hook the battery up positive ground and you will be 
good to go.

Later cars have an eletric tach which needs to be worked on too, but yours 
is still mechanical, so OK.
