I have a Pertronix Flame Thrower II coil on my 65. Can I hook it up to the factory coil wire? It supplies resistance when running but not when cranking.
12. If converting from a point type ignition, remove any resistance wire, or
ballast resistor that may have been previously used.
If a resistance wire is present: replace the wire with a 12-gauge copper
stranded wire. Most resistance wires begin at the engine compartment
side of the
fuse block.

It appears the pertronix system runs on 12 volts not 7-9 volts like the OEM system.
So a by-pass of the resistance wire from the ignition switch is needed
Yup. Bypass it. It drops the volts to stock coil down to ~6-7Volts so that it wouldn't burn the factory points out. But will have problems with pertronix coil with the low voltage. Go straight from the key switch, and bypass the stock wire.
I have a Pertronix Billet distributor with the ignitor II module. So, I don't have points. I'm glad you brought that up though. That way anyone that reads this thread will know about the issue with points.
