Ever deal directly with Mahle in Germany?

[Rob 930]

I have an unusual project involving the need for some vintage GT3 race pistons that are either unobtainable or very expensive from Porsche Motorsports. I have several options stateside that I'm considering, including JE/Nickies through Charles Navarro, Mahle Motorsports US pistons (which are somewhat different than the German pistons they would replace), or working with the used stuff I have. But before I choose one of these paths, I want to see if anyone has a direct connection with Mahle in Germany and could share a contact. PM is fine.
