Hi omaron,
Here simple solution for you.
open '../templates/{YOUR TEMPLATE}/link-display.tpl'
*** find following code
{if $config.broken_links_report}
| <a href="javascript:void(0)" onclick="reportBrokenLink({$link.id})">{$lang.report_broken_link}</a>
{/if}
*** replace with following code
{if $config.broken_links_report}
| <a href="javascript:void(0)" onclick="reportBrokenLink({$link.id})">{$lang.report_broken_link}</a>
{/if}
{if $config.link_rating}
<br /><form action="view-link.php?id={$link.id}" link method="post" style="margin-top: 10px;">
<select name="rating">
<option value="">Site rank</option>
{section name=rating loop=$config.link_rating_max+1 start=1 max=$config.link_rating_max}
<option value="{$smarty.section.rating.index}" {if $smarty.post.rating eq $smarty.section.rating.index}selected="selected"{/if}>{$smarty.section.rating.index}</option>
{/section}
</select>
<input type="submit" name="rate" value="{$lang.rate_link}" />
</form>
{/if}
*** save and close it.
