function uninstallPart(acpids, pids, acid, t)
{
    classes.Frame.serverLights(true);
    if (t == "c")
    {
        classes.Lookup.removeFromRaceCarsXML(acid);
        getURL("lingo: executeCall \"uninstallpart\", \"acpids=" + acpids + "&pids=" + pids + "&acid=" + acid + "\"", "");
    }
    else if (t == "e")
    {
        getURL("lingo: executeCall \"uninstallenginepart\", \"aepids=" + acpids + "&epids=" + pids + "&aeid=" + acid + "\"", "");
    }
    else
    {
        classes.Frame.serverLights(false);
    } // end else if
