I'm surprised that a search found nothing as this has been a common topic,anyway it's really easy.I bought an E15(non turbo)dizzy and a CA20 High energy coil.Firstly you swap the blade drive on the pulsar dizzy for a gear drive A series one,just knock the locating pin out and drill the pin hole out to suit the larger A series pin.Then take the A series dizzy adjuster plate and adapt it to fit onto the pulsar dizzy,some filing and drilling of new holes required to make it fit and to be able to adjust timing.Finally stick the pulsar dizzy in your A series motor and forget about points for good
