Viano Grand W639 Side Skirt Part No?

[mca422]

Hi, does anyone know the part number for the OEM side skirts from the Viano Grand Avantgarde (W639)? No matter which MB dealer I call, they can't order it unless I have the part number or a VIN so they can look it up. I can't provide a VIN because I have a 2014 Vito (MWB) and the part belongs to the Viano Grand. They are happy to sell it to me but they need the part number. It's very frustrating! Can anyone here help with the part number? Or if you have a Grand, I would be in your debt if you could call a dealer and find out the part no

P.S. I know there's aftermarket skirts, but I like the OEM look best...
