@ OP: I think you want to have madness armor have the same model as amber. So go in the cs, load shivering isles with it NOT being the active file. Find the madness armor and and amber armor and open everything up. There will be some biped model stuff, just set the paths of madness to the same as amber. Or are you not already using custom models for amber/madness? Then you'd have to extract files from the shivering isles...
