I actually work for them
Safelite is cool because they have a lifetime warranty on any glass they install if it is the back window (Backglass) its literally as easy as tanking off a panel and replacing a normal door glass if it is the rear passenger door A.k.a the door behind the front seat passenger than samething very easy if it is the small glass that is behind the rear passenger door like that little quarter glass its pretty toyotas are very easy to replace any window and work on one of the reasons I got it. Ive replaced all windows on the 4runner at one time or another so I can say cleaning up the glass takes longer than the actual job
