I am pulling apart a 6 cylinder 200ci. I could not get the last bolt loosened from the head, so I decided to take things off from below. After getting the oil pan off I saw the sending unit (all this is brand new to me). Since I have the engine on my handy-dandy engine stand I thought I would turn it over so that I could take the sending unit off standing up straight. As I did this I heard a metallic clanging on the concrete floor and found a six inch (approximately) long six-sided shaft. It is thicker than a normal pencil, but not by much. There are on threads. Both ends are the same shape. I obviously have no idea where it fell out of. Any help.
Thanks
