I pulled the seal on one of my windows in hopes of finding a replacement (there are absolutely no identification marks on the window). So far no luck yet. the bottom of the seal has UV damage so for now I'll flip it over so the UV damaged part is at the top. In order to get the seal back in I have to stretch it a bit. Only problem with stretching is that I end up with "too long of a seal" and then it wont work because of that "issue". What's the secret to getting these seals to fit?
