Broken steering wheel horn switch

A customer of mine has a '93 Roadmaster and I noticed the left horn switch is broken. Two tabs are broken inside the holder and has a slim piece of plastic on the other side holding it on. It does work, but looks like it could break off completely.

Does anybody know if I can get a switch or switch kit for this without replacing the whole air bag assembly or what?

Thanks, Formzy

The switches are available, but one is broke, better buy both ..the other one willbreak shortly. Been there.......
