Repairing gas valve on old regulator?

[thegame310]

Hi all,

So I have this old regulator, that I think works okay, but the gas valve just spins around and doesn't actually turn on or off. I can just replace this portion right? Take it to my local homebrew store and find the part? Order online? Thoughts?

You should be able to take off the bad shutoff and replace the whole thing with a new shutoff
