There is the one around the door itself, and the second one along the top of both doors, and down to the windshield. There is also a bottom seal on the door, that is held on by screws under the trim.
I have R&Rd the driver side upper one, and changed the front driver's side door surround...all of them are basically the same. I have an excellent driver's side front seal for sale ($35 shipped), and could probably get the others. I can give you a break on shipping for more than one.
When mounting the seals, the top one goes behind the tubular part of the door surround seal. If you allow it to be on top, it will cause the door seal to leak
