1995 blazer emergency light switch

I have a 95 4wd blazer. my emergency light switch on my steering column snaped off inside. the button popped up and hit the roof. i have temporarily stuck a piece of metal in there so my taillights and parking lights dont flash all the time. But i plan on selling my blazer soon and i want to get that fixed. anyone know of a site where i can get this replaced??? or what i should do?? and also, if anyone is interested in buying a blazer contact me.
