Custom content while retaining vb header and footer

[ctrlbrk]

For one particular page of content, I want to retain the VB header, navbar, and footer --- but in the middle of the page instead of showthread/post I want to be able to display my own non-VB generated content (say for instance, an iframe).

I was thinking there has to be a way to call something, like misc.php?do=custom, and then somewhere I can upload a new Style template that has what I want it to display. There is probably even a way to just call a template directly, but I am having trouble...

I am having trouble figuring out how to do this. Would someone be so kind to point me in the right direction?
