This 7075 aluminum conversion plate will adapt the factory 2012 Camaro ZL1 Automatic to a CV Adapter Plate. 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.
