I have purchased new weather-stripping from my Mercedes dealer for my 1974 240D 115. I removed the old weather-stripping on the front passenger door and tried to install. After carefully pushing the new weather-stripping in the door channels. The weather-stripping didn’t quite fit. About 3” to long. Is there any way to “shrink” the weather-stripping before the install? Or should I just return and order another. Any tips would be helpful.
Thanks,
Eric
