If you are talking about the clear plastic catches on the door jamb to hold the doors in place, here are a couple of ideas.
Some people have used Velcro on the door and the jamb. Or you can call Heartland parts department after the holidays and order a newer design set. If you have the originals in your 2006, they have since been changed. It is important that when you install them that they are aligned with the door.
The doors will not stay in place in transit.
