I have these parts for my 2007 v6 mustang but unfortunately cannot afford it anymore so I am forced to sell my car and all the parts that I have. The T-Lok and 3.73 gears are brand new (still in the box) and the tuner was only on my car for a few months (still have the box and manual). The T-Lok is made by Ford Racing, the gears are made by Motive, and the tuner is the Diablo Sport made by Predator. Asking 600 dollars OBO. All of these parts cost me 750+ dollars so this is a good deal. All reasonable offers considered, no low-ballers.
