This took a lot of work, but I took an original passenger door lock cyl, turned it over and installed in drivers door. You have to find another passenger locking latch mech, to take apart to use the locking links, which have to be cut and flipped,welded ,and install in the drivers latch assembly. It took a little time, but it looks original, key on drivers door goes in upside-down, but works great. Both doors have same lock under handle. Just can't unlock or lock from inside. It was an idea that worked for me.
