Have never seen the core plug for manifolds sold separately.

you will likely have an easier time going to the auto parts store and getting a freeze plug based on OD. you can also use a rubber expansion plug if there is enough room between inside and outside of manifold.

Did the manifold freeze or did this corrode out?

Go to NAPA, make sure to buy brass

And the correct terminology is "core plug"
