I bought the diff in Tennessee from a guy who used to work at a ford production plant. He said it belonged to a 2000 mustang cobra svt. The thing is that in 2000 they never made the cobra, they only made the cobra R which had a 351w in it instead of the 4.6. They had a few prototypes of the 2000 cobra svt and some extra parts but they all got scrapped because the car never went into production. He said that it was left over from the spare parts of the 2000 cobra svt prototypes and he got to keep it. So it's essentially the same as a 99 Cobra diff and has the 28 spline output to the halfshafts but the number on the VIN tag is non existent because a 2000 Cobra svt was never made.
