Help:2005 E320 4matic Wagon Brake Callipers

I've been trying to order new front brake callipers for my 2005 E320 4matic wagon, but when ordering there seems to be a lot of variants which is causing me some confusion. Are there really any difference between the different callipers?
It is to may understanding that all the E320's from this year have the same front brakes, but the websites all seem to indicate sedan and 4matic specific variants.
I don't want to have to go through various purchases and returns before I get the right ones.
Your help is appreciated.

The mb caliper i picked up at the mb dealer says made in france in the box which eliminated the heat from the prior version
