Q204 Clarification

I should be more specific, as I guess my initial question is pretty ambiguous. I mean the clawed arm graft from fiend folio. It gives a +4 untyped bonus to strength for anything done with the arm, including wielding weapons. If you had 2 of these arms, would the bonus stack to +8 while wielding a weapon in both hands?
