Yes, it says .030 in the ad. NOWHERE did YOU specify size. Then in a post "up there" ^^ you seemingly say "stock" as to refer to STD size. So, the jury is still out for what you need. I gave you all the information regarding those pistons right off the bat that toolmanmike just posted, yet "HERE WE ARE" still talkin about it. So WHAT EXACTLY are you wanting to find out?
