'96 Manual Side Swing Out Window

I have a friend that broke out the right rear manual swing out side window. Do the windows come from the factory with the mounting clips glued on? He is thinking about getting the side glass from a junk yard but can't figure out how to get the front mounting clips off...do they come off from the inside? From the junk yard can he get all three mounting clips? Can anyone shed some light on this?
Thanks,
