I have a 1969 Mustang FB with a 351W toploader 4 speed. I know the right bell housing is a C5TA-6394-A. But I have a C5AA-6394-B. If I use a 164 tooth flywheel with a 10 1/2 inch clutch will this work on my 351W? I am not sure if the casting is the same for fork or starter location. Anything else that I would need to be concerned with?
