Hi! I am entertaining the idea of installing the rear facing seats on a 2014 MS 60 with power liftgate. Any suggestions for shops that would do the job in the Los Angeles area? I have seen recommendations for SF and other states, but not SoCal. The plan would probably be to find the seats used and bring to them, and I would also try to find the bumper reenforcement, although that might be trickier and the shop might have to get that. I know that this could potentially be done without the help of a shop, but I'd rather be safe than sorry... Thanks!
