yeah i have some. (Used but seem good) but i have an add up on my local cl for kitty parts and get asked all the time for a piston and rings or just rings.. i dont want to part with mine, even though i have 3 sets .. if i could find where to get some i could even out the supply and demand,, and yeah i seen the one on e bay.. these little pistons, i cant believe are going for so much $ i just rebuilt my lil ones kitty. i bought a half a sled with about 5 boxes of parts for 90$ so far i got 2 complete running motors. sold alot of stuff on e bay already. i cant believe how much some of this stuff went for. if u have 1 local like a 72 or 73 and u can get it for cheap jump on it. u can part it out and do pretty well. that or if u got a little one re do it, there pretty neat, i have xtra parts if u need. thanks for the tip though. im gonna try and give him a call and see. ill also give u a buzz a little later. i had to ground my boy last night from the cmp. he gets slick and uses the kindle so i had to disconect the router.. ((i wonder where he gets it from)) lol
