Old O-360 with new dynafocal mount?

[Eric12]

Good morning. I have a 1950s Lycoming O-360 freshly overhauled. It was used with the old style dynafocal 1 mount (nominal 2" cups).

Does anyone know if this engine is compatible with a dynafocal 1 mount with the larger cups (nominal 3")?

Thanks for any input.
