Getting back to the original question posed in the title of this thread, no Bishop signed or did not sign "Vatican II". There were 16 separate docuмents, each of which was voted on and signed separately from the others, which comprised what we call "Vatican II". Various Council Fathers voted for or against individual docuмents, various Fathers signed or did not sign individual docuмents. No one voted yay or nay on "Vatican II" itself.
If memory serves, 4 Council Fathers voted against the Constitution on the Sacred Liturgy: I believe these were Cardinal Alfredo Ottaviani, Cardinal Antonio Bacci, Bishop Antonio de Castro Mayer, and Archbishop Geraldo Sigaud. I have no idea whether any of the 4 signed the docuмent after it was passed over their votes of "non placet."
Two of the most controversial docuмents were Gaudium et Spes, the Pastoral Constitution on the Church in the Modern World, and Dignitatis Humanae, the Declaration on Religious Liberty. A fairly significant number of Council Fathers (I believe at least a couple hundred) voted against these. Once again, whether they still signed them in the end is a different question.
It is a fact that Archbishop Lefebvre at least voted against the Declaration on Religious Liberty, and I believe he also did not sign it.
But once again, getting back to the original question, no one voted yay or nay on "Vatican II".
