I have a good 28 Spline 8.8 TL carrier from a Cougar XR7. It was pulled with 74,081 miles on the car, and looks to be in very good shape with no broken clutches. I would recommend replacing the TL clutches and upgrading the spring while you have it out of the car, but it would not have to be done. This is a direct bolt in for any year Mark VIII, and will put power to both wheels! $150 and I will take care of the shipping in the US.
