The fabric on the B pillars and the upright frames on either side of the windshield of my 99 ML need replacing. Can that fabric be bought...and where? Does something like that have a part #?

I'm not sure about the material, but the pillars do have a part number. Go to your dealer (the only place available) and they can order it. I believe they are somewhere in the range of $175 each. I also purchased some from a salvage yard. Hope this helps!!!
