Suzuki 2 Strokes

Just noting someones post in the for sale section for T20 seals I remembered I bought a full set, about 2 years ago now, still have hem unused, for about $40.0 I think. From memory I got them by accident from a guy who bought something from me and mentioned he has a set after we talked T20 for a while. Anyway pretty sure the outside ones you can match up at good bearing supply outlets, I have not tried getting the inner ones but surely the race boys would not rely on draining up stock to keep their bikes on the track, so what would they be doing for centre crank seals?
