Removing the tailgate glass
 

Anyone know how to go about this in a 92 fullsize?

Lower the tailgate and remove the access panel. raise the window with either a jumper wire to the motor or manually. then you should see some nuts going through the window holding it to the regulator arm. before you remove the window make sure to remove the defroster leads if it has rear defrost.
