No. I don’t know what actually fits. For example I read that the 603 fan and shroud goes lower than the 617 version so the fan would hit the transmission cooler connections. But I have no way to verify that.

Job #1 is just to know if the tabs for the shroud are common across 617 and 603 w126 cars.
