1930 Ford Sedan Slam Job - Need Pointers

I thought I submitted this yesterday but apparently it didn't stick...

I'm building a 30 model A Sedan with my sons and we're in the process of channeling the body so it is even with the bottom of the frame rails. I'm looking for some pictures of successful projects so I don't have to invent this, and avoid doing it 5 times. Any of you guys have any pictures that you can share on what kind of structure you put together? What kind of tubing used? Etc.

Much appreciated.

Freezing in SD.

 

It's called channeling. Do a search I'm sure you can find something.
