The FAA is mandating retrofit via AD. From the above linked FAA press release:
The U.S. aircraft that will be retrofitted include approximately 2,730 aircraft belonging to the A320 family of 900 airplanes, 50 A330s, 965 Boeing 737s, 60 Boeing 747s, 475 Boeing 757s, 150 Boeing 767s and 130 Boeing 777s.
I don't recall the compliance time, although it is relatively long due to the difficulties in the installation.
