hey mate
got some here. pulled them out of a 20V block and threw them in a box... haven't touched them for about 2 yrs.
got plenty of oil on them though.
shall we say.....if you come and get them, you can have them if you bring me 2 x 2L of cokacola, as they are of no use to me.
i also have a brand new set of late model bigport pistons (20mm bearing thing). but i dont think they will suit your application.
btw you realise 20v and smallport pistons are different yer? they just both have the 20mm gudgeon pin.
