Using Joomla Wrapper Module With Gridbox

I'm trying to work with Gridbox and another extension (VikRestaurants). I love the flexibility and styling of gridbox but I need to allow VikRestaurants to be the main page in order for the filtering to work.

So here's what I'm trying to do:
- Create a Menu Item for VikRestaurants (this works)
- Use Gridbox as the default theme (this works)
- Create a page with some nice blocks with information. This can have instructions or other content relevant to the menu item (in this case an order form) being displayed. (I can create a separate page with Gridbox which looks good)

**Integration of the two items (this is tricky)
- I would like to display the content of the page I created in gridbox in the menu item page
- for example, display page id=2 in a module position that is supported by gridbox - say "top-full-width"
- I can do this with an iframe wrapper (Joomla Wrapper Module) and assign the module to the correct menu item
- The problem is that the displays twice.
- I can't seem to (easily) subtract the header off of the gridbox page that I'd like to display in the module position.

Do you have any ideas on how I can directly reference a page without showing the header?
If I use the link: "index.php?option=com_gridbox&view=page&tmpl=component&id=3", this kinda works but loses all the formatting. If I remove the "tmpl=component" then this displays the header.

I'd be fine with creating a new template view override for the specific page. I've looked in a couple of places and can't seem to find where this might be.

It may be something super simple, but if you can help point me in the correct direction that would be great.
Thanks for the help and have a great day,
