I've modified this add-on to display the preview text only. First you need a template called full_cms_in_comments_thread:

{vb:raw previewtext}<br />
	<span class="cms_article_readmore"><a href="{vb:raw page_url}">{vb:rawphrase read_more_phrase} <img src="{vb:stylevar imgdir_cms}/read_more-{vb:stylevar right}.png" alt="{vb:rawphrase read_more_phrase}" /></a>
	</span>

And this is the new hook code:

if (THIS_SCRIPT == 'showthread' AND $this->thread['forumid'] == $this->registry->options['vbcmsforumid'] AND $this->post['postcount'] == 1) {
	$result = $this->registry->db->query_first("
	  SELECT cms_article.pagetext, cms_article.threadid, cms_article.htmlstate, cms_node.nodeid, cms_node.userid, cms_node.url
	  FROM " . TABLE_PREFIX . "cms_article AS cms_article
	  INNER JOIN " . TABLE_PREFIX . "cms_node AS cms_node ON (cms_node.contentid = cms_article.contentid)
	  INNER JOIN " . TABLE_PREFIX . "cms_nodeinfo AS cms_nodeinfo ON (cms_nodeinfo.nodeid = cms_node.nodeid)
	  WHERE cms_nodeinfo.associatedthreadid = ". $this->thread['threadid']. "
	");

	if($result) {
		$contenttypeid = vb_Types::instance()->getContentTypeID('vBCms_Article');
		$allow_html = vBCMS_Permissions::canUseHtml($result['nodeid'], $contenttypeid, $result['userid']);

		$bbcode_parser = new vBCms_BBCode_HTML(vB::$vbulletin, vBCms_BBCode_HTML::fetchCmsTags());
		$pagetext = $bbcode_parser->get_preview(fetch_censored_text($result['pagetext']), vB::$vbulletin->options['default_cms_previewlength'], $allow_html);
		$result['previewtext'] = strip_bbcode($pagetext);

		$attach = new vB_Attach_Display_Content(vB::$vbulletin, 'vBCms_Article');
		$attachments = $attach->fetch_postattach(0, $result['nodeid']);
		$bbcode_parser->attachments = $attachments;
		$bbcode_parser->unsetattach = true;

		$templater = vB_Template::create('full_cms_in_comments_thread');
		$templater->register('previewtext', fetch_censored_text($bbcode_parser->do_parse($result['previewtext'],true,$result['htmlstate'])));
		$templater->register('page_url', vB_Route::create('vBCms_Route_Content', $result['nodeid'] . ($result['url'] == '' ? '' : '-' . $result['url']))->getCurrentURL());
		$this->post['message'] = $templater->render();
	}
}
