Sure, all the seals are available. Whether they fit or not is a different question, the originals were pretty soft and the reproductions are sometimes firmer, causing problems with the doors closing or what not.
There should be a seal that runs along the bottom of the door, secured with a dozen or so clips. It turns and runs partway up the front of the door. Then there is another piece of the same type of seal, that runs along the curved section where the door meets the scuttle, and partway down the front of the door. It uses 7 more clips. Between the two of them, you shouldn't get any water. Then there are fuzzy seals (more trim than seal, really) that run up the inside of the door at the front and back.
Check out TRF P/N 650046 for the bottom seal, 603257 for the top, and 552877 (available in different colors) for the fuzzy seal. You'll need two each of the rubber seals. They also have door seal kits with all the seals and clips in one package, P/N RFK903 for black, RFK904 Red; RFK905 blue or RFK906 tan. The kits are shown on sale at the moment, so this might be a good time to buy.
However, are you sure it's coming past the door? There are more seals inside the front fender that are sometimes overlooked. If they leak, you can get water (or snow) that mysteriously comes out of the dash onto your leg. I drove without them for a lot of years (stuffing cloth and whatnot into the opening) before discovering how it was supposed to work.
