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 bell housing. 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.
