I just got finished replacing the front rotors and pads on my '94 E320. When I removed the rear wheel, I found that those on the car were not of the ventilated type.

Mercedes has given me ventilated rears, based on my VIN number. It does not appear that these are interchangeable with the solid ones. Am I wrong? The ventilated rotors are much wider in cross section, so I assume the calipers would never fit around them.

Can anyone shed some light on this for me?

Thank you for any help!
