just change 6 volt to 12 volt with a alternator. every thing works ok runs fine. need to reduce volts to gas &temp. when key is trun on motor not runing ballast gets hot to the touch, is this normal... have not run motor for long time yet. to see if it it gets way to hot. it is wired from +side of coil to igiton switch...

Not sure what you did or used. Some did get hot working properly as they were reducing volts by consuming it to achieve correct running voltage,

Note they are or many were made of porcelain and placed on just metal firewalls. True - There to allow whatever full battery can offer while cranking then reduce voltage to not burn out points or stress other ignition items for just "running."

Note, you can tell that system is happy with voltage and the condenser if the points with some use/miles do not transfer metal from one to the other - that's good. TMK there is no known life expectancy of the condenser (so told in trade school) to keep a good one but this system is now somewhat custom vs factory engineered so take a peek now and then. Points should be cheap but have been fooled before. LUBE THE CAM IN THERE! The plastic bumper that rides it causes points to make gap smaller and can be hard on the cam. You lube just a smear of dialectic grease ahead of the way it spins.

Points are fine IMO just need looking at and some attention now and then. Hey - that's all we had back when and the world didn't stop! Might be a hunt but owning dwell meter is much better than a feeler gauge for those. Might be hard to find but they should still be somewhere,

If it helps I believe all 1960s Mustangs/Falcons were 6v dash items (gauges) reduced to make accurate. You can get parts for those cars forever it seems if you are pulling your hair out.........
