OK, now I'm losing my mind. Several times I checked the pin at the plug behind the engine and was getting 6.5V. I was just about to button up the wiring and decided to check again and now its reading 12.5V. What gives

Under what conditions were you checking? Engine on or off? If off, you'll see full battery voltage with points open and about 6V with it closed. With the engine running, you should see something like 1V below battery voltage, which is the average voltage with points being opened and closed rapidly. Your meter may read something different (due to its averaging a variable voltage over time) but something well above 6V and somewhere below full battery voltage.
Just verified:
Engine off, duraspark and coil completely disconnected, and reading directly at the engine wiring harness, I am reading 12.5 volts.
My distributor doesn't have points.

Karl Kustoms sells a magnetic pickup distributor for 50$ I have been using it for 6 months now and it has preformed great. Model KPPJM6606 search google with that # and it will come up. I am using it with Duraspark type setup.

Good. That's what you should be reading.
How would I verify that the resistance wire in the harness exists and is giving the correct voltage as to not burn out the coil? I thought I should be reading 6.5V from the engine harness.

The voltage reading will change depending on whether or not the coil is charging, as the draw will reduce the voltage. 12.5V with the DuraSpark disconnected and 6.5V with it connected is what I'd expect to see.

With the coil disconnected, you don't have a complete circuit, so are reading voltage potential (battery voltage). Measure with the circuit complete and go by MIdlife's earlier post. As for verifying if the resistance wire is present, since you read 6.5 volts at one point, it's there. If you really want to dig deep, you could find both ends under the dash and do an ohm reading. A standard wire will show 0 ohms, and the resistance wire will show something, although I don't remember how much.

This is what I was looking for. Just didn't google enough last night. All is well: 5.8V at the coil while doing the test and and 12.8V with engine running; 14.1V at the battery with engine running.
I ended up buying a cardone distributor off amazon for $75. We will see the quality when it arrives.
