put the seal on the window,set the window on the piece of metal that holds the seal ,then take 1/4 " rope and feed it into the rubber where the metal should go then pull the rope gently towards the inside of the car from the inside of the car working back and forth slowly and carefully while someone with a whole lot of patience presses the window toward the car with open hands while you pull on the diffrent sides of the ropes trying to go evenly the whole way until the window is fully installed,you can use a wooden paint stick to help it along as you go the rope may seem stuck but just gently pull it in several directions and have the helper back off on the pressure and it should go in nicely.you can use windex as a lubricant or a mixture of soap and water.Good luck, You can do it!!!! just take your time
