240 d oil coolermy mercedes is a  240D 1976  
chassis number 115117- engine number 616916-

the original is a steel oil cooler (BEHR) and the number on it which I am guessing is the OEM part number  is .

Answer
    I've asked around, and no one that I deal with has access to a new one of these.  You might want to try some of the on-line places that sell used Merc parts.  Or, given that the cooler is made of steel, you might want to see if a welder could repair it.
