How to tighten rear glass???

I have a 98 Passport and the rear lift glass rattles like a B#$ch! I used weather striping before but that only works for a little bit. Is there a way to fix this? Thanks!

Isuzu has a TSB about this. Its TSB number SB00-11-S005 and involves putting some rubber o-rings in where the glass bolts to the hinges.

Isuzu part number for the o-ring kit is 2-90503-920-0.
