Best place to brace
 

I have a few body mod's to do on the Elco and would appreciate you're guy's thoughts.

I need to replace both floor panels (under seat), raise the tunnel for the T56 and fab a new firewall w/pocket to set her back. Of course I'll be doing one area at a time.

Where would the best place be for the bracing to be a minimal PITA yet provide the required support.

The body's sitting on a bare frame.
