Using a program such as WinRaR or 7Zip (For Windows, it might be the same with a Mac though), right click on the mod file and click 'Open with ---'. Go into Assets>lotr>armor. Then take out the armour piece you wish to edit, and edit it.

I think that's what you want anyway ;). Someone should make a video on it.
