I am putting together my interior and realized I don't know what I am doing......

The old inner door fuzzy (cat whisker) had what I think are metal staples holding the top of the door panel and door fuzzy in place against the inner glass. The problem is the new ones I got don't have any holes or openings. This is a set I got from Nick and I know a bunch of you guys got them too. So what did you do?
Thanks,
Dennis
