Heavy duty Chrome-Moly bearing support plate. Factory plates might work in stock applications, but, once you start putting some serious power down you will quickly find the weak spots in your drivetrain. Catastrophic failure could be the end result. With gears and other internal transmission parts slowly disappearing for these cars the last thing you want to have to do is pay through the nose for used parts. Protect your investment with a chrome moly end plate that will keep things together in your transmission when the going gets tough. Fits A465/A525/A520 and A555 Transmissions.
