Hazard Switch Missing...

I recently Purchased a 1995 MC and I am in the process of fixing it up.. and one of the things I noticed is... I have NO hazard button..

On the top of the Steering Colum.. there is a Hole.. I am assuming thats where the Hazard Button was?

what is involved in replacing it?

thanks

Buy or get the button, should snap down into place unless he retainer in the switch is broken.
