If the hood is the same, the fender is definitely also the same.
EDIT: Aaand... I take it back. The fender will be different because the second-gen W126es used different side trim:
I'm not sure if the cladding can be swapped or not.
BTW, you'd probably be best off posting questions related to diesel cars in Diesel Discussion, since it gets a whole lot more traffic than this here gasser side does
