Naekid isn't that far off the mark. When we ordered our TJ in 1996, we ordered the full and 1/2 doors (with both tops), only the full doors arrived. The dealership forgot to place the 1/2 door order (on purpose, but that's another story). So we looked into the door options, buying them from the factory. Guess what? The 1/2 doors (and full doors, similar price, but it was 1996 & 1997) were $900 EACH, unpainted. Needless to say, we didn't get them. I bought a set of CJ-7 & 8 soft doors and retrofitted them for the TJ. Don't work that bad, but don't seal as well as I'd like. Still better than nothing in a rain storm. I have seen the aftermarket tops (looked at one this am in a catalog) for $1,400, but it was the Targa top (removable front section). I'm sure you could find one cheaper new and a lot cheaper used.
