Actually - the hooks are there on that page you linked to. Not sure why you are having issues (could be teh apostrophes around 'posts' in the line before the hook), however you can do it manually. Edit your postbit legacy, search for

<div class="eti_postbit"> 
{vb:rawphrase 'posts'} : {vb:raw post.posts} 
    </div>

add

<div class="eti_postbit"> 
{vb:rawphrase vbookie_cash} : {vb:raw post.vbookie_cash} 
    </div>

immediately below it. You should also disable the vBookie: Add Cash to Postbit plugin if you've manually added the template edit.
