6mm Carbon apex seals
Education, education, education!
The twin dizzy 12A (the true 12A) was fitted with 6mm Carbon-alloy compound apex seals, as found in the RX2 and RX3 pre late 1973.
I know because I have one in my 1971 series 1 RX2. It also has twin side seals on the rotors and no REAPS or emissions gear on the exhaust.
The Mazda part number for the 6mm carbob apex seals was 0839-23-131.

You can use 3mm if your grooves are too worn out to accept 2mm or for a few other reasons. I forget, but 3+mm carbon seals might be part of a slew of things necessary for high rpms. You machine out the grooves even further to fit in the 3mm seals. But in general, for common road use, 2mm is better.
