I cut out the worst part of it (back half of the roof). It's 18ga. steel so it will match up very nicely with the .040 aluminum I plan on using for the quarters, door skins, and deck lid. So far by my calculations I've taken off over 300 pounds of ugly fat from the body. When I got the car it had no seats or anything in it so I can't really estimate how much lighter the pieces going in the interior will weigh. Getting anxious to set the body back on what's left of the original frame and see where I'm at for weight!
