Need to replace my stock rusty floor pans

I'm looking to replace my floor pans on my 70 dart drag car. There's too much crusty and thin areas, so rather than patching id like to frame the area and replace it with nhra minimum thickness steel .023.
If anyone has any pictures of their cars flooring/framing I'd like to see them.
As the car sits I have 2×3 subframe connectors and the cage is built already.
I'm kinda just out of ideas at the moment.
Thanks
