You can do it yourself, it is basically a rubber seal with push pins on the backside that pop into holes around the perimeter of the door. The door seals may be costly. Call 1-800-LMC-TRUCK Tell them the part you need. I have used them in the past and their prices are the best. You may be able to just order 1 door seal....I'm not sure. Ask them any questions and they should be able to give you the answers.
