I am selling a rear out of a 2005 CTS. It has ~60,000 miles on it, the rear diff bushing is in great shape. It was replaced due to noise. I figured a V owner may want it to build it, it has 3.23's gears as you can see in the second picture. I'm asking $250 obo +shipping. I'd prefer to sell local but if you're willing to pay for shipping I have no problem shipping it. I'm open to any offer, if I don't sell it within a month or so it's going to the scrap yard.
EMAIL ME if you're interested.
