I've been looking at upgrading my ignition set up with an MSD 6201/6A box. I was told I need to use a phasing rotor kit and I have a Mallory Unilite Mechanical Advance dist. Does anyone know if the MSD 84211 Rotor Kit work with my Unilite?

I called the MSD tech line and they couldn't tell me if it would or not

Any info would be much appreciated, Mike
