hi we have a 93 subaru legacy with some serious water leakage in almost all of the windows (including sunroof). i assume that the rubber seals/gaskets need to be replaced. anyone have problems with this? any suggestions before going the 'replace rubber' avenue? we got a qoute from a sub shop and they said that new rubber costs $140 PER WINDOW...that seems like a bit much. anyone know of an online store that sells for cheaper? we live in seattle so this is a bit of an issue. thanks in advance.
