More likely that not...........you will not find a shelf piston that meets your requirements.....time to contact J&E, Mahle, Weisco, Venolia, Ross, ask them what they can do for you
Thanks I went to the J@E website but can't find their emailI can. I found a piston order form sheet to fill out but no email address to send it back. I'm in Australia so I'm asleep when they're open. Does anyone know the email address thanks
