I picked up one of the early 6/2017 Dialed In LE's the other day and had to take the two speaker panel screws out as mentioned.
Here is a pic of what I saw when opened. Is there a pic or a service bulletin online that will explains how this should look/fix?
Glad I found this thread about taking out the two speaker screws as that was the ON:Y way the backglass was coming off.
