280 leaking rear main--where to find gaskets?

[oldan]

I am in USA and having difficulty finding a supplier of 280 rear main seal.
Engine has to be pulled so I will want to replace other gaskets such as valve cover and oil pan gaskets. Can not find those either. Maybe I just have to order through the local MBZ dealer and pay thru the nose?



Was going to sell the car and then the seal blew. I am guessing this will cost about $3000 to do at a shop and am wondering if I can get my money back or would I be better off selling it as a project car in hopes a good DIY can
do this a lot cheaper. The car is in great shape other then the seal.
