The stash coordinates are gained by looting a corpse. The location of the stash is on the ground floor of the factory where you access Lab X-18 in the Dark Valley. The main factory building consists of two sections, one large room with a high ceiling where you first enter, and another section running north and south with three floors. As you enter this second section, the stash is on your left in the corner of the room.
