Er i dont know. I believe all mk3 polo con rods are the same, except the 1w ones as they have a longer stroke. So maybe all 1292cc pistons are the same?

oryt thanx for all replys so basicaly as far as i was aware all con rods are defo same, no that some 1 on hear sed that crank shafts could possibly be ever so slightly different but so small you wouldnt notice, and i thought that pistons wer specific to g40 for compression  ???
