Here is a quick little guide on how to manually update the items.txt for glitchy's model swapper.
First thing you want to do is have 2 websites open.
World of Warcraft :: Allakhazam.com
Wowhead: LF1M -- You!
You technically only need allakhazam's open but I use wowhead to search for screenshots of the items I want to swap.
First go to allakhazam's and search for the item you want to add. For an example I am going to use the shield Bastion of Resolve. Just below the picture you will see a XML link. Click on that.

Once you click on the XML link you will see what looks like alot of HTML code. Scroll down a bit, you are looking for 2 different numbers. DISPLAYINFO and ID. Write those down.
Now open up the items.txt in the modelswapper folder and scroll all the way to the bottom. You will see a number followed by a name then another number. You add the ID,ITEMNAME,DISPLAYINFO
So it looks like this.

Save and close. Then simply swap items as normal.
If you have any questions or if I skipped something you don't understand feel free to PM me. I'll be doing another guide on setting up more item sets and custom item sets so you can just swap quickly as needed.
