DatsunSSS will post a picture of *one kind* of A12GX piston.

Same part number == same part.

The Datsun A12GX engine came with two different pistons:
* High compression: same piston as A10 engine.
* Low compression: a unique piston

Quote:That happened to almost all Nissan part numbers. It doesn't mean a lot in this context. It just means that the later A10 engines came with the updated A12GX piston (H23xx is the Datsun 1200 GX model).

Again, 12010-H1001 was the "normal" A12 piston set. It was also used by the "low compression" A12GX.

It seems we have "discovered" a whole new source for high compression GX pistons -- I knew it was just a matter of time before we would find a good use for A10 engines.
