Gentlemen,
The 1955 and 1956 FYB FOM flex-plate was replaced by the 1957 flex-plate, B7A 6375-A for service, The 1957 flex-plate includes three reinforcement rings (B9AZ 6A366-A). I cannot find any service info as to how theses rings are placed.
Does anyone know or have the service information as how the flex-plate and rings are assembled in correct sequence to the crank flange?

It must have been released in a period SERVICE LETTER.
oldmics?
