you have to measure the length of them and there is a spec for replacement or reuse. I will send you the specs but i need the next three numbers in the engine number 603***

Maximum bolt length from base of head to end of threads on your engine is 52.9mm, brand new they are 52.7mm. If the bolt is any longer than 52.9mm you must replace them with MB bolts. I would not trust aftermarket ones in this case.

It depends on the model year of your engine. If it is up to manufacturer date of 11/90 then torque to 30Nm and then turn and additional 90 degrees. If it is between 12/90 and 10/92 torque to 45Nm and turn an additional 90 degrees. If it is as of 11/92 torque to 40Nm and turn an additional 90 degrees. (also if you are reusing the old bolts subtract 5Nm from the 1st stage torque spec since the bolt is already pre stretched)
