You do have the small one.
Panel change requires changing the lower enclosure also, best done by procuring the entire assembly including the pivot arm assembly. It does not affect the canopy with the exception that it takes a good bit of time to install the pivot arm assembly so that the canopy fits correctly.
Been there- done that.
