vB3 vB 3.8 Profile Tabs template issue
 

So I'm looking at editing a theme quite similar to the 3.8 default, but I'm using the .tborder around the site for a thicker border than the default.

This is great and works everywhere (except within the tabs when viewing a users profile).

I've been looking for hours on how to find out where I can edit a template to get rid of the class="tborder" on each of the tabs themselves.

In Memberinfo I see the:
Code:

$template_hook[profile_left_first]
$blocks[visitor_messaging]
$blocks[aboutme]
$blocks[stats]
$blocks[friends]
$blocks[infractions]
$blocks[contactinfo]
$template_hook[profile_left_last]


However, I cannot seem to find where I can find and get rid of the
Code:
<li id="aboutme_tab" tab_id="aboutme" class="tborder tcat" fixed-width="86" style="width: 86px; display: block; background-position: 0px 0px; ">About Me
All I'd like to do is get rid of that tborder and replace it with another class. I can do that easily, if I could just find where its pulling that info from.

Any ideas?
Thanks in advance for the help.
