Unless you are doing a by the book the restoration, I believe the 6ca might be a better option. The point sets are easier to adjust because of independent mounting, but you would have to mount condensers somewhere. Given the amount of bikes converted to EI, I would think you could find a used set somewhere. You would also need the auto advance unit.

Everything will be alright in the end.
