When fitting the electronic distributor I bought from E-bay I found there was no rotor button. I tried both the gh600 & gh606 buttons & both were to big to fit the shaft. They would turn 360 degrees & would not lock the button in place. I got the car running by bodging one of the buttons, but needed a permanent solution, because it was a real dodgy fix. Emailing the supplier did no good, so I replaced the distributor with an N12 dizzy, then took the new distributor to Stuart at SWR. He said the distributors were made for forklifts, so maybe a forklift supplier had parts to fit. I found such a distributor & he was able to supply 2 different buttons, one taller than the other. Both fit the shaft perfectly. Unfortunately I have lost the piece of paper with the parts numbers, but if you have bought one of these distributors, at least you should be able to find rotor buttons & even distributor caps.

That's the great thing about forklift supplies -- they still stock many A-series engine parts. Also they carry some parts not normally sold in-country (such as Mitsubishi distributors in places where Hitachis were used in the cars)

This ebay.com.au A12 distributor looks like a Mitsu unit (bolt-down cap and 2-side-bolt advance unit). The cap & rotor was used by JDM 1200s and certain mid-80s Nissans in AUS and USA

b310gx - put up some photos of the ACTUAL distributor - outside and under the cap

I have quite a few of these electronic dizzys and could give you a button
Each are slightly different
