Oooo...that's a nice pod, Dave!
I have one of those cheap JC whitney deals on the other side of the steering column under the dash.
I have never attempted to look but just on the surface those 2" gauges may fit but I would worry about the bracing/etc. behind the face of the area you are talking about. Plus I would cringe just cutting through the factory dash.
Just for reference, here's a pic where you can see the area Dave is talking about. Don't mind the fuzzy dash cover....
