6volt coil wire sizes

[SAXBY2]

Is 12 Ga wire ok for the ignition to coil and terminal box to coil terminals ?

12ga seems a bit large. I like 18ga wire, but if that is what you have, us it.

Yes. Will work very well.

It's a little overkill in size but it certainly won't hurt anything I would make nice bends so it will look really neat on the firewall!!!

16-AWG is what Ford used for most model A circuits. You can use larger if you want but the wire has to fit the notches in the terminal box cover.
