remove door panel, drop window all the way. Raise up a bit and you'll see two spots for bolts to go in. Also while your at it unscrew the window channel and feed the new window guide into it and screw it back down. Its very simple to do this. Anyway once the new window is in, you may have to unbolt the window guide in the front of the window, just push it back a bit to get the window in between the guides. Bolt it back up. roll it up a few times and your good to go.
