2012 AC evaporator change

I’m replacing the evaporator and looking for some video help. Specifically the mount bolts for the box. One video shows them on engine side of the firewall but I think that was an earlier model. When I get the dash out, will I see them from inside?
Thanks in advance

Well with no replies to my post, I pressed on and found that the box comes out with the dashboard frame after removing the dash. No bolts going into or through the firewall.
