has anyone replaced there rear window ? any tips?

 

i havnt replaced the rear window but i have a 98 silverado with tinted center slide window and when i had my subs in the back seat the window popped out and i had to re-seal it. but what year truck you got? i know if you have a 97-98 like me you can order a brand new rear window assembly pre-tinted and all u has to do is pop the old one out and glue the new one in.
