How to change bibliography style from [1] to 1

Question

I know that several people have already asked this question, but for some strange reason the suggestions are not working.

I have tried inserting:

\makeatletter
\renewcommand\@biblabel[1]{#1.}
\makeatother

into the preamble of my .tex file, of the .ltb file, and of the style file that I am using, however nothing changes the references. This is and example of what has been tried:

\documentclass[noheadings]{uncthesis}  
\usepackage{amsmath,amssymb,amsthm,slashed,amsfonts}

\makeatletter
\renewcommand\@biblabel[1]{#1.}
\makeatother

\begin{document}
Alan Sokal~\cite{Sokal96} recommends Bourbaki's
text~\cite{Bourbaki70} for a gentle introduction to set theory.
\begin{thebibliography}{plain}
\bibselect{Bib}
\end{thebibliography}
\end{document}

The corresponding Bib.ltb would be:

\documentclass{amsart}
\usepackage{amsrefs}
\begin{document} 
\begin{bibdiv}
\begin{biblist}
\bib{Bourbaki70}{book}{
title={Th\'eorie des ensembles},
author={Bourbaki, Nicolas},
date={1970},
publisher={Hermann},
address={Paris}
}
\bib{Sokal96}{article}{
title={Trangressing the boundaries},
subtitle={Toward a transformative hermeneutics of quantum gravity},
author={Sokal, Alan},
journal={Social Text},
volume={46/47},
date={1996},
pages={217--252}
}
\end{biblist}
\end{bibdiv}
\end{document}

I have also tried inserting:

\makeatletter
\renewcommand{\BibLabel}{%
  \hfill
  \Hy@raisedlink{\hyper@anchorstart{cite.\CurrentBib}\hyper@anchorend}%
\thebib.%
}
\makeatother

However, this yields the error message

2063: Undefined control sequence.
\BibLabel ->\hfill \Hy@raisedlink 
                              {\hyper@anchorstart {cite.\CurrentBib }\hy...
l.2063 \begin{thebibliography}{plain}

Are there any other suggestions? Thank you!

Since amsrefs is being used, a redefinition of \BibLabel is needed:

\documentclass{article}
\usepackage{amsrefs}

\makeatletter
\renewcommand{\BibLabel}{%
    \hfill
    \Hy@raisedlink{\hyper@anchorstart{cite.\CurrentBib}\hyper@anchorend}%
    \thebib.%
}
\makeatother

\begin{document}
Alan Sokal~\cite{Sokal96} recommends Bourbaki's
text~\cite{Bourbaki70} for a gentle introduction to set theory.
\begin{bibdiv}
\begin{biblist}
\bib{Bourbaki70}{book}{
title={Th\'eorie des ensembles},
author={Bourbaki, Nicolas},
date={1970},
publisher={Hermann},
address={Paris}
}
\bib{Sokal96}{article}{
title={Trangressing the boundaries},
subtitle={Toward a transformative hermeneutics of quantum gravity},
author={Sokal, Alan},
journal={Social Text},
volume={46/47},
date={1996},
pages={217--252}
}
\end{biblist}
\end{bibdiv}

\end{document}

Just for the record, here's the original definition:

\newcommand{\BibLabel}{%
    \hfill
    \Hy@raisedlink{\hyper@anchorstart{cite.\CurrentBib}\hyper@anchorend}%
    [\thebib]%
}

A little explanation on why the redefinition of \@biblabel doesn't work with amsrefs: \@biblabel is a kernel's command and amsrefs doesn't use it to format the labels in the bibliography (amsrefs uses its own \BibLabel command); that's why redefining \@biblabel when the amsrefs package is used goes silently into oblivion (in particular, no error message will be produced) without any visible effect.
