It should fit ok as long as you use the engine mounts from the 82 frame.
In your pics in post #10 the first and last are not ignition parts.
Pic #1 is where the alternator goes.
Pic #2 are the points.
Pic #3 is advancer parts.
Pic #4 is the alternator stator.
I would test the stator white wires for ohms. Look at the plug on the end of the wires Number them 1, 2, 3. Using your VOM or Volt Ohm Meter use the lowest ohm scale.
Touch the leads together, this will give you a reading. Remember this reading.
Not test the white wires, from 1-2, 2-3 and 1-3. They should all read the same. >9 ohms. Your reading may not be that. So now you have to subtract the first reading, just touching the leads, from the test reading.
On one of my meters the leads read .7 ohms. Using this meter and when I test the white wires I get all three testing at 1.6, subtract the .7 from the 1.6 and you get .9. This is the actual reading on the wires. My other meter the leads test at .1 ohms.
If your stator test out ok then all you need is a good rotor. These and a regulator and a rectifier and your charging system will be a good one.
On the ignition parts you have I might set them aside. Get a Pamco from Mike's item #14-0907 uses an ok coil but the plug wires can't be easily replaced. Item #14-0913 has a better coil with replaceable plug wires.
Both of these kits come with an advancer rod.
Just install and you good to go.
