I was on the same mission, and was talking to a14force last night, and he said the A series electronic dizzys are very very very hard to find (and i quote "they are like rocking-horse ####"). HOWEVER, he mentioned that an electronic dizzy out of an E15 engine (pulsar) fits with a couple of modifications
And also, apparently 'dick smith electronics' (in NZ) supplies something called a "high energy ignition kit" which turns a points dizzy into electronic somehow (cost around $NZ70)....hope this helps.
