Technical Mallory Mini-Mag Bendix replacement coil?

What are my options for a good replacement coil? Looking for a factory appearing coil.

Bendix

Also, if anyone has a good 12v Drag-Pak version for sale I may be interested.

 

there's 1/2 a chance that you can replace that coil w/ something out of a tractor mag--each brand is diff and some have almost the same iron core size...

 

Found this today, know nothing about electrical stuff.
