OEM Saddle Bag Install - 2012 NC

Searched around for threads on installing the oem bags on a 2012, however I can't seem to find any. Does anyone have good info on the install process, I guess there is some trimming work to do?

Post #16 of this thread has links to the actual Honda installation instructions: http://nc700-forum.com/forum/nc700-mods/1970-nc700x-accessory-user-guide-installation-instructions.html. This should tell you what the process is.
