Will the '64-'79 Mustang pressure plate have the correct bolt pattern to match a '49-53' flathead flywheel? Am trying to get a pressure plate/disc to work with Ford top-loader 4 speed and my late flathead. I see Speedway offers a complete kit with the correct shaft size & spline count but am not sure if it will bolt to my flywheel. Have tried to get Speedway to answer other questions for me but have been unsuccessful for the most part.
