passenger door lock

does anyone know where i can find the part to replace the door closing mechanism for a 92 jeep cherokee? the part that actually keeps the door closed was broken (door was jammed shut for awhile, now the part is removed entirely) on the passenger side... jeep manuals dont seem to list the name of this part so im not sure how i would go about replacing it. help???

you might wanna try your local jeep junkyard, if you have the broken piece they can find the right part.
