Cummins 4BT / 6BT adapter plate to install a GM transmission such as a 700R4.
This is a Cummins 4BT / 6BT adapter plate to install a GM transmission such as a 700R4 on a Cummins wave ring. Pictured with the wave ring. What you are buying is the flat adapter plate. Make sure you have the correct space between the adapter plate and the torque converter, usually about 1/8 inch. If for some reason you don’t we can build short torque converters. The picture without the wave ring is the correct picture.
