This steel conversion plate will adapt the factory 2005-2014 Mustang (Diff. Flange) (Auto or Manual) / Ford GT (Axle Flange) to a 108MM 6-Bolt CV Pattern. This steel conversion plate has a special anti-rust coating to prevent corrosion. This is the same adapter plate as can be found on our line of pro-series driveshafts for these vehicles. They are precision machined on centers to maintain perfect centerline and will fit onto the centering-pin that is on the factory differential flange. Includes all necessary hardware to mount the adapter.
