I ordered this bottom seal a month ago, and finally got around to trying to install it yesterday. It didn't fit. The \"T\" on the ends is 5/16\" wide. My old seal was 3/16\". I tried trimming a little off of each side of the \"T\", and I did manage to get about 3/4 of it down the door. Then I tore it. So much for that. My biggest problem was with the aluminum track where it had been crimped before. I had straightened them out, but the side that I was trying to slide it into had a little jagged area that caused the rip. It's a nice seal, just check the width of your track before you order it.
