Clipping Problems?

[Miseracord]

I've been working on several WoW models pieced together from other models and such- basically my problem is that on various figures (just the standard human model) parts of the shoulderpads conflict, usually the left, it removes a part from it. This is probably due to some sort of overlapping, right?

i can't seem to get it to work out right exactly...any ideas people?

thanks again
