Rufus,
The fenders are original. It took a lot of work to get them straight again, and the bottoms were rusted out (like most Z cars do) as were the rockers forward of the rear wheels. All the bodypanels are original except of course the rear panel (see link in my signature for pics) and the bumper, which is 'glass, and the hood, which is obviously later model 280Z with the vent holes.
All the bodywork was done by me up to, and including, the primer. The actual color was sprayed by my neighbor, at his bodyshop. He didn't charge me, even though it took him from noon to 3am to finish it, but I gave him a bottle of booze and $500.00. I did the color sanding and buffing too.
