It helps to have two people. One inside one outside. also buy some little plastic pry bars HF has them and so do some hardware stores. For the rear glass fitting over a flange put the rubber on the truck first. The one thing Super Glue, Eastman 910, Isocyanurate (SP)does work on is gluing the ends of the rubber together. Steele told me the orange hand cleaner without grit in it works real well as a lube.
