It's extremely easy to get working and if your community listed in your signature is correct you got it working

Just for future references for those wondering -

Follow all the instructions listed in the main post. Only changes are as follows -

Modify the Postbit_legacy in your template:

1. Admin CP -> Styles & Templates -> Postbit Templates ->
postbit_legacy

Find

<vb:if condition="$show['avatar']">
		<a class="postuseravatar" href="{vb:link member, {vb:raw post}}" title="{vb:raw post.username} is {vb:raw post.online} now.">
			<img src="{vb:raw post.avatarurl}" alt="{vb:rawphrase xs_avatar, {vb:raw post.username}}" />
		</a>
		</vb:if>

After that add

<vb:if condition="$post['field#']">
<center><img src="http://avatar.xboxlive.com/avatar/{vb:raw post.field#}/avatar-body.png" width="75" height="150">
</center>
</vb:if>

Where field# is the field you put in for the GT. That's it.

My own personal edit for one of my clients is

<vb:if condition="$post['field5']">
<center><img src="http://avatar.xboxlive.com/avatar/{vb:raw post.field5}/avatar-body.png">
</center>
<vb:else />

		
		<a class="postuseravatar" href="{vb:link member, {vb:raw post}}" title="{vb:raw post.username} is {vb:raw post.online} now.">
			<img src="{vb:raw post.avatarurl}" alt="{vb:rawphrase xs_avatar, {vb:raw post.username}}" />
		</a>

</vb:if>

Which shows the 360 avatar first if they so have one otherwise show the forum avatar they selected (or uploaded)
