I have a vinyl garage door. Installed by a contractor about 8-10 years ago. It is color matched to the siding. The seal is worn and needs to be replaced. I do not know what manufacturer of door this is. (cannot contact the original installer). The seal is rubber and attached to the bottom by bolting an "L" shaped mounting trim to the rear of the door (see photos)

Any ideas and where to order this seal?

Thanks!!
