Wiper Installation

Hello,

I have a '97 Jimmy, and the wiper blades are shot. I bought some new ones, but they are on their own assembly, and not just blades.

I was wondering how one would go about installing these, if it can even be done. The stock assembly has that clip that the blades pivot on, but the new ones only have a hole in the middle for a pin. Do I need an extra part or something?

Any help is appreciated :)
