How to attach center console to trans tunnel

Happy New Year, all!

I am getting ready to embark on designing and building a center console/ armrest for my 79 CJ7 and am looking for suggestions on how to best secure it to the floor of the tub.

I intend to start with a piece of 1" sq stock across the front of the tub, just below the dash panel. From there, I am planning to construct a framework similar to the one below:



My problem is, I am not sure how to connect it to the tub. I would like to bolt it, for ease of removal/ modification. The tub/trans tunnel are full of different contours and elevations (see photo), so for simplicity's sake, I will have to stay above the highest point.

I've seen where some people have built 'pedestals', but this seems cheesy to me...



I've also seen some that have been built all the way back to the rear seat riser formed into the floor (see pic), but I think that might impede rear seat access (not that it is used much)....



Any thoughts??

Thanks in advance!

Maybe use crimp nuts, or weld brackets to the floor with threaded holes that the console bolts to, like a subframe.

Is it a steel tub or fiberglass?

I like Rivnuts for steel, but you can also use larger (#12 or #14) sheet metal screws. I mounted the console on my Nova (below) using just four tiny #10 sheet metal screws, two near the front corners and two near the rear corners, and it stayed in place just fine like that. How big and how many fasteners you need depends on the design of your console and whether or not you are going to climb on top of it.

The tub is steel and I don't expect to be climbing on the console.

Theses suggestions bring up another question, though:

How to 'address' the inevitable holes in the floor of the tub.
Upstate NY conditions tend to take full advantage of any 'chink in the armor' to start the spread of rust.

Also, would anyone have a photo of how they've made similar connections?
(bolt (or screw) through the framework, or use tabs of some sort?)

Here is some of mine. Nothing really shows the attaching since that's I was showing just the general layout and design. Front is connected to dash with a bracket on each side and rear is screwed to the floor. I beat on this and its been solid for over 3yrs now.
