Looking for a postbit legacy template that looks like this...

[Triky]

You have to add a set of tables in your postbit_legacy template.

For example:

<if condition="$post['usertitle']">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center" style="border-bottom-width:1px">
<tr>
    <td class="thead" width="100%">

<div class="smallfont" style="text-align: center;">$post[usertitle]</div>

</td>
</tr>
</table>
</if>

And change the blue code [Create your own vBulletin tables].
