Bought a new E320 wagon...LOVE IT! Picked up a Becker fiber optic CD changer, same as MB sells, $500 cheaper (Bought from SW Stereo in NC, Great guy, very knowledgeable).

Question: What mounting brackets does MB use to mount changer vertically in right rear wheel well next to first aid kit? They are not included with the Becker changer.
Is there a part number for it? Any help would be greatly appreciated!
