Add all GArrow files to your existing addon folder using OpenIV the use addonpeds to add to the game.
Also attached is my suit for the Batman mod, I use a base of 100-150hp to gauge a normal persons durability. So all of my missions the suits will be balanced. [ EX. Batman would NEVER beatup Superman etc ]
