late model gear is same on a15 and a12/a14.

its same for early a12 too from memory (used a early a12 in my old mid mount a12 worked fine).

im using e15 dizzy, just wired it in, same coil and with resistor too. works 100%.

great spark.

I was thinking of making a spare one up for future use as they arnt rebuildable like the bluebird ones (curcit board etc).

Do you need specail tool to drill the clip hole in?
