How to add text links / navigation area

I am in the process of migrating from my old (enhanced) wwwboards to vbulletin 3.6.5 / vbseo. I am going to run the forums side-by-side for a while (I hope) and migrate users across.

OK, I have the old wwwboards (on /sub-directories/main.html) plus message archives and information pages (all pure html) which I want to keep for a while. To do this I need to link to at least some of the old pages from vbulletin's pages, but I can not find anywhere to accommodate this. I deally I would like to add a text link navigation area at the bottom of all of the vbulletin pages.

Any ideas if and how I can do this (nicely and aesthetically)?

Thanks in advance.

running side by side is a horrible idea, not only for SEO but for maintenance issues.

do a back up, run the Impex using a NEW database for vB, move the old files to a new directory, like "/oldforums" using the old database. if you need to reference back, you can, but all your traffic will be hitting the new vB installation.
