Replacing My Garage Door Seal

Techie? Maybe not so much, but this is a project I'm going to appreciate next winter when I'm doing projects in my garage (some of which will be techie). In this video I replace the rubber seal on the bottom of my garage door, which would be pretty simple if the garage floor at the entrance was level. Unfortunately the concrete slumps on both ends, so I had to add shims to contour the seal to follow the concrete. Hope you find something here that is useful and interesting!
