ah ok you speak about the antracite barriere (i thought you were talking about the blue one in my post) it's an old part , maybe i'm wrong but i think you lose your time to ask that to the ds , it's a bit hard to find , seriously i have only 20 like this and i can say i buy kg . if you find some in ebay you will pay sending everywhere to get a lot like this . Have you see the one from the farm , it could maybe be good for you ? JL
