Here's a website of a guy doing a concours frame-off restoration of a Hemi Roadrunner. He did most of his own 1/4 panel, floor and other section replacements early in the project.
He did a great job of documenting what was involved and has great photos. He also talks about lessons learned and had to redo some things.
You are going to have to ask yourself:
Do I have the right equipment?
How good are my sheetmetal cutting skills?
How good am I at aligning body panels?
How good are my welding (especially spotwelding) skills?
