Replace Window on 00 Tacoma

All, Need to replace the window on my xtra cab 2000 Tacoma. This is the one behind the drivers side window in the xtra cab section. It is attached at 3 points, 2 forward and one toward the rear with a hinge so it can be opened. Doesn't appear to be any easy way to remove the two forward attachment points to replace the window, Help ! Tks
