I've never had to provide proof of ownership for any Euro part. My local dealer used to have the best dealer MB parts man that ever lived. He would look up anything for me and place an order, no problem.

His name was John Vinson and he had the good old fashioned customer service attitude. He has sense retired and I have sadly learned that he now has some health issues.

They can sell you anything they want. The problem is that most of them are not interested in spending a little extra time to look up a part number so they can provide customer satisfaction.

I think your solution is to somehow come up with part numbers on your own where you can. Give them the number and tell them to order it. I expect that the guys on FastLane could get these parts for you, but I'm not sure.

Good luck,
