The sealing rails (or felt strips if you wish) are MB 115 725 09 65. That part number gets you a piece about 2.2 meters in length. In otherwords, plenty to do one door on a pagoda. The current list is $62.00, my price $45.53. OK, it's not cheap but it's really not that bad. One of wholesalers also sells the stuff but they sell "Mercedes original" so I suspect a perfect aftermarket substitute does not exist.
