How does the wiper system work on an a body?

My wipers do not move at all, but I would like to get them working so I can drive my car without worrying about rain.

I took the wiper motor off, when I move the wipers by hand I can see and feel a straight bar, parallel to the firewall, moving from left to right. But that’s all I know.

What are the parts that connect the wiper motor to the wiper blades?

I found this animation http://auto.howstuffworks.com/wiper1.htm is this how our mopars work?

Either way does anyone know where I can get the parts and what parts to get in order to get the wipers moving?
