Does anyone know where in Zen Cart code the <br /> between rows of specials gets written?

I can see where it is writing the actual content of the seperate divs for each special but can;t figure out where the break gets scripted to split the, in my case, 3 column rows from each other.

You can see the issue I'm trying to reslove here: zen.napiers.net - the special offers list at the bottom of the page. When the specials titles and images are of differing heights some unexpected layout issues occur caused by the float:left of the divs. I need to change the <br /> between the rows to <br style="clear:both;" />

Any pointers appreciated

thanks
