Brake Light Switch

Hi Everyone. What is the easiest way to change the brake light switch on a 95 sierra 4x4?

I still haven't figured out that clip yet. Help

Nevermind, I found a garage to put it in for 40 bucks. Thanks anyway.

Well I believe I am on here by myself. But anyway, the garage put my switch on and my brake lights worked for about a week, then I got to messing around with the switch, I unclipped it from the push rod and it started working again, for about 1 day, then I messed some more and noticed the lights would come on if I pushed it to the side a little, so I took a piece of printer paper, folded it up and slid it between the push rod and the switch and the lights have worked ever since. Remedy for a quick temporary fix.
