What is this bar called. #7 in diagram

[c good]

I think it's a rear sway bar or stabilizer bar but can't find a name for it and the diagram doesn't say what it's called. Ugghhh.....apologies...can't get correct diagram to attach. It's the bar that goes from side to side just behind the differential. Will work on getting diagram posted. Thx...c good

Found it....It's a "Track Bar". http://www.gmpartscenter.net/auto-p...gine/rear-suspension-cat/rear-suspension-scat

Commonly called a panhard bar also.
