1982 240D floor pans

[kessler1492]

Hello I have a 1982 240D Mercedes benz, interior is like brand new as well as the engine one owner who was an older lady in Illinios, all I need to do is fix the rust on it and it should go another 10 years if I take care of it, My question is this, I'm having a hard time finding floor pans for the car I did find floor pans for a 126 chassis, is that the same or is it compatiable with mine, I think mine might be a 123 chassis, not sure, would like to get replacement parts if I can any ideas?
