OK this is going probably going to sound goofy but here it is. I have this conversation piece on my bench at work which is a bunch of pistons stacked on top of each other (the largest on the bottom to smallest on top). Right now I have pistons from Tractors, BB Chevy, BB Doge, BB Pontiac, SB Chevy, Volkswagen, Corvair, 2 cycle generator, KX250, CR125, CR80, Weed Wackers, and RC cars. What I need is anything 50cc to 500cc (except 80 125 250) to complete this mess so I can permaently attach them togther (keeps getting knocked over). If anybody has a piston that's willing to send it to me I'll pay the shipping and give you a few bucks. Who else is going to give you something for that piece of junk? Email me.
