When ordering parts for my '75 450SL I am often asked for the engine number.

Two engines were used that year. They are 117.982 and 117.985. No plate exists anywhere on the car that indicates the engine number. Not even the original service and warranty booklet has the engine number.

My VIN is 107 044 12 021781. The car was manufactured 06/74 and sold 11/74. It was titled as a 1975 model. It has the original engine.

Does anyone have an MB listing that shows the engine number on this car?

Thanks, Steve Guinter
