Does anyone know the length (in mm) of the bolts that connect the exhaust manifolds to the exhaust pipes. I am talking about the bolts that mate to the m8x12 copper nuts. I believe the bolts have 13mm heads. The Mercedes EPC system shows it as a "screw" with part number N 000931 008217 but I cannot find that part anywhere. I have been searching all day and cannot figure out what length bolts to buy (and cannot get an accurate measure on the bolts already in the car). Any help would be appreciated. Thanks
