Just an update:  I did get a hold of Lynch's and he's going to sell me a pair of Canadian reproduction panels.  He also mentioned though that he has a pair of originals that he's going to use to start making their own reproductions.  So, for those of you looking for them in the future, check them out.  <!-- m --><a class="postlink" href="http://www.lynchfarmstractorparts.com/">http://www.lynchfarmstractorparts.com/</a><!-- m -->

Thanks to everyone for their help!
