I am looking at some online parts catalog and get confused at the designation of engine# ? How do you determine what the engine number is? The car I am inquiring about is a 1987 260E with the 2.6L engine W124 body. The excerpts below is from an online aftermarket vendor. How do determine if it will fit, where do u look this info up from your car? Apparently the number #035731 and #016911 are engines number. Does Mercedes stamp a number on every engine it manufactures? TIA
