Using $navbar in the postbit template

[GetGamer.com]

I'm trying to put a link to the parent forum on the line below the thread title in this particular style: http://www.bigblueball.com/forums/sh...ad.php?t=31068

In the end, the line following the title should read:

Posted by name | timestamp | parent forum

I was able to get the forumid, but I can't figure out how to get the forum title (this in in the postbit template). I hit on the idea of using the breadcrumbs from the navbar (which I'm not using in this particular style), and I edited the navbar template accordingly, but when I use $navbar within the postbit template, nothing shows up.

Any ideas on how to proceed?
