I have done back glass in 80's trucks this is how we did it....
1 NEW rubber and a long string
2 put NEW rubber on glass
3 grease outside grove on rubber, the part that will set on metal cab frame.
4 put string in greased outer track.
5 have helper hold glass on outside of cab with as much as possiable in outer grove
6 get inside trk and pull SLOWLY on the string as it pulls rubber over window hole opening.
7 when entire rubber in fitted onto cab window hole use windex to clean grease off truck window.
how I have put several sliding windows in place of regular ones in a commercial shop working mid 80's to mid 90's trucks
I HAVE NOT TRIED IT in a task force.
The key here is NEW rubber that is soft
Good luck
Brad
