While there's not an official list, if you search here on the forums it has come up several times and you will find a rough list of the general things that would need to be attended to. Off the top of my head here is a quick list:

1. 12v Solenoid (the starter is ok to leave as is)
2. Reverse the wires on the amp meter (if you have one) because of the change from + to - ground
3. Find a 12v generator/regulator from a 55/56 or use a modern Alternator. If you do the later, then you will need to fab up a lower bracket (see my Project Blog for details on that). Also can the remove the 6v regulator.
4. Replace all the bulbs with 12v version
5. you will either need a heavy duty 12v to 6v convertor to run the blower motor, or do as I did and get the 12v motor from a 55/56. Different blower housing, but the motors are interchangable.
6. You will also need 12v to 6v convertors for the dash gauges, the radio, and the clock. Those are pretty cheap to buy, and you could always just have the radio converted on the inside and add a solid state vibrator at that time.
7. You will also need a 12v coil, and a ballast resistor. Make sure you hook the coil up with the negative side connected to the distro.

Optional things:

8. Replace the horn relay with one from a 55/56.
9. Replace horns with one from a 55/56. The 6v horns will work, but will have a different tone on 12v.
10. Swap cig lighter element with the 55/56 element.

Hope this helps.
