Door cover strips

Hello.

because at my already the rust appears so slowly at the lower door edges and corners I want to paint the doors fresh. No problem, actually, but... I can't find a new door cover for the V8. The large bars with chrome strip are still impeccable, but the lower door covers are already rotten and I urgently need 4 new ones. But wherever I look, marketplace, ebay, at Audi... I can't find one. And making the rusty groins again on the fresh doors is stupid.

If anyone has an idea where to pick up some or who else would have helped me a lot.

Greeting Benjamin
