You're welcome to use the fairings I made for Velcro Saturns, so long as you put them in a different location (don't over-write them).
In answer to your question, I'm no Anim8or expert, but my usual method with Milkshape is to select by vertex one-half, hit delete, save one half, then hit undo and delete the other half. Not too cosmic, really, although you're on your own for selecting by vertex in Anim8or.
