Someone else on the forum will probably be able to remind me, and then you, of the model number, but all of the electrics, including the switches were made by Delco for GM, and I think they'll probably match right up with a Cadillac from that time frame. I'd be very surprised if they aren't still made.<o:p></o:p></span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black">Lance<o:p></o:p></span></p></div><div id="Signature"><div><p class="MsoNormal"><span style="font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p></div><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#0C64C0"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#F3901D"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#0C64C0"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#C82613"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#F3901D"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#C82613"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:#C82613"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:14.0pt;font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-size:18.0pt;font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p><p class="MsoNormal" style="background:white"><span style="font-family:"Arial",sans-serif;color:black"><o:p> </o:p></span></p></div><div class="MsoNormal" align="center" style="text-align:center"><hr size="1" width="98%" align="center"></div><div id="divRplyFwdMsg"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black"> Rovernet <</span><a href="mailto:rovernet-bounces@rovernet.org"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">rovernet-bounces@rovernet.org</span></a><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black">> on behalf of Jonathan Present via Rovernet <</span><a href="mailto:rovernet@rovernet.org"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">rovernet@rovernet.org</span></a><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black">><br><b>Sent:</b> Monday, October 20, 2025 11:41 AM<br><b>To:</b> </span><a href="mailto:rovernet@rovernet.org"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">rovernet@rovernet.org</span></a><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black"> <</span><a href="mailto:rovernet@rovernet.org"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">rovernet@rovernet.org</span></a><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black">><br><b>Cc:</b> Jonathan Present <</span><a href="mailto:present.jonathan@gmail.com"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">present.jonathan@gmail.com</span></a><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:black">><br><b>Subject:</b> [Rovernet] Seeking left rear power window motor for 1970 3500s</span> <o:p></o:p></p><div><p class="MsoNormal"> <o:p></o:p></p></div></div><div><div><p class="MsoNormal"><span style="font-size:11.0pt"><br>Sent from my iPhone<br><br>_______________________________________________<br>Rovernet mailing list<br></span><a href="mailto:Rovernet@rovernet.org"><span style="font-size:11.0pt">Rovernet@rovernet.org</span></a><span style="font-size:11.0pt"><br></span><a href="http://rovernet.org/mailman/listinfo/rovernet_rovernet.org"><span style="font-size:11.0pt">http://rovernet.org/mailman/listinfo/rovernet_rovernet.org</span></a><span style="font-size:11.0pt"><o:p></o:p></span></p></div></div></div><span>_______________________________________________</span><br><span>Rovernet mailing list</span><br><span>Rovernet@rovernet.org</span><br><span>http://rovernet.org/mailman/listinfo/rovernet_rovernet.org</span><br></div></blockquote></div></div></div></body></html>
