if its anything like the MK2, 1st you have to remove the main glass as theres no clearance with it in. 2 bolts hold the window to the lifter, then it should pop out. You might have to remove the seals at the base of the glass tho. Then as said remove the metal post, there will be a bolt/screw at the top and one at the bottom. Pull it forward, then swap the glass!
