Hi all. For those of you looking for specialty pistons; try EGGE Obsolete Engine Parts. http://www.egge.com or info at egge.com or, 1-800-866-egge. They cast their own pistons and can vary lots of things. Happy hunting. Ron Haskell rdhaskell at juno.com Riverside, California USA http://albums.photo.epson.com/j/AlbumList?u=3009370&f=0
