I won't swear to it, But
If i recall correctly, the 5th Gen mirror mounting stud pattern is different than the 4th Gen pattern.
The only way to find out, would i think be to take off either front door plastic cover that hides the mounting studs. Then using something like a 4"X 4" cardboard cut off. Press the cardboard against the 3 studs to get a impression of the mounting pattern.
Then find someone with a 5th Gen Ram & ask them if it would be OK to compare impressions.
I have a friendly relationship with the guys in the Parts Dept. & sometimes they let me look at new parts to compare against, but even the parts counter has a line of customers lately needing something or other.
