Transmission Fitment: this driveshaft will only fit Mustangs equipped with a Tremec T-56 Magnum XL six-speed transmission. The driveshaft will not fit with the stock 5-Speed transmission.
Fitment notes: For applications lowered 1-2 inches (standard lowering springs), the E-Brake cable bracket must be moved 1.5 inches away from the driveshaft tunnel. For Mustangs lowered 2 inches or more, the E-Brake cable bracket must be relocated as described above, and the two metal flanges must be bent flat or completely removed. On 2005 to early 2008 Mustangs, the factory stiffening plate will need to be flattened down for proper clearance.
