I have a 98 1500 with the solid glue in window. I know there are 2 types of windows used in these year ranges. The glue in ones and the push in ones. I'm looking to replace my solid one for a sliding window for access to my camper on the truck. Can I use a push in sliding or do I have to find a glue in sliding window and go through all the bull of removing a glued in one from a junk truck??
