dj,
I have both a 400e and a 400se with M119 engines. I can tell you without a doubt, the M119 engine is TIGHTLY mounted into the w124 as apposed to the W140(s-class).
I dont' have the figures or distances from the radiator to fan clutch since I'm at work, but since we both have w124's with m119, I'm guessing they are the same.
I've attached the pic for the w140 with the m119 engine on changing the radiator... it's an m119 but the fan shroud is only one piece.
