Let me know if this works, in my "head" it does

Find in "search_results":

PHP Code:

<if condition="$action == 'getnew'">$vbphrase[new_posts_nav]<else />$vbphrase[posts_from_last_day]</if>
        </if> 


Replace With:

PHP Code:

<if condition="!is_member_of($vbulletin->userinfo, X)"><if condition="$action == 'getnew'">$vbphrase[new_posts_nav]<else />$vbphrase[posts_from_last_day]</if>
        </if></if> 


Replace "X" with the usergroups you want to allow. Separate them like this "1,2,4,5,6" for multiple groups.

Let me know if this works.
