I just ran a check on the V4 to V3 morphs and they don't work for some reason, I don't think I ever got them to work.  But copying morphs from V3 to V4 does the trick.  As I mentioned, it's just a way to recycle V3 morphs to V4.  And I'm making a self-correction, this body type will accept V4 textures, not V3.  Essentially, you're outfitting a V3 body with a V4 head and textures.
