Kit Includes: steel plate, hardware & thread-locker. If you are installing a later model automatic transmission in your 1955-1956 classic with a 265 V8, which has no provisions for a block mounted starter, you will need this plate. This starter plate mounts between the rear of the engine and the transmission providing an original style mounting surface for your starter like the one in your stock bellhousing. You can also use this plate in 1957 models with broken starter mount holes or pads. Use in a 1957 model will require using a 1955-1956 style transmission mounted starter. Will work with all popular automatic transmissions. Use of a 168 tooth flexplate is required. Installation hardware included.
