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
I don't know if this will give you any assistance or not, but here is what I did to mine. I replaced the rear pans in my 64 Valiant, Vixen. It starts about here and goes on for a few pages. I know it's an early A and not a later one, but they are very similar in floor structure.
