Here is a link to a topic I started last year where I posted pictures of a Charger we did that was pretty rotted away. I also explained how I supported and braced it.
I put on a roof, floors, wheel housings, rear body panel, quarters, doors, fenders, etc. Lots of fabrication needed for those pieces you just can't buy, or to make the pieces you can buy fit like they're supposed to.
On this car the original hood, trunk lid and one rocker were retained.
