I used a plastic strap off of a respirator mask actually haha. I put it on 3 years ago as kind of a temporary hold but it worked so good that I decided to just leave it. It goes into the door jam and used a self tapping screw to hold it in place between the 2 peices of weather strip. I just cut a small slice in the outside peice and slipped it through. I've done others on friends vehicles using hose clamps with a self tapper running into the pillar though, that seems to work just as well.
