So the trunk arrived but was damaged. Surprisingly enough the company doesn't want it back, but they are sending me a replacement. So I am waiting on that one to arrive, however I have put on the base plate for the trunk to mount too. It fits on top of the luggage rack and secures nicely with the provided brackets.
I will have to make some changes once the fixed trunk arrives I will have to modify the backrest. Basically what I will be doing is cutting the backrest off the luggage rack so I can move this base plate forwards a little and make room for the backrest of the trunk.
I didn't get any good pictures putting the saddle bags on, however it was pretty straight forward too. We had pictures but we had technical issues that caused the pictures to get deleted.
Anyway, when the trunk gets here I will get it mounted and make sure to take lots of pictures to show how I did it.

The trunk wont be big enough for a full face helmet, but it is going to help me out a LOT when I have to make store runs, and it's going to provide a lot more comfort for my daughter when she is riding on back.
