I think Sparrows came a little later on but maybe a pod of 2.75" free fire rockets and at least the nose section gun ports for the 50 cal MGs would work.
The first Sparrow prototype was tested in 1952 and it entered service in 1956. I'm pretty sure they were available to this airframe during it's time of service.
