I think everything has been covered here, but I know how confusing it can be. Perhaps my experience can help.
In 1980 I began to build a neoclassic roadster which I am still driving. The donor car was a wrecked 1979 Cougar and the body tub was 1964 MG Midget.
The bucks (plugs) for the fenders were built on the outside of the body tub using a buck / mold / fender process. I started using scrap 1/4" steel rod welded together in the shape of the fenders. This was covered with welded wire mesh, (maybe 1/2'), coarse cloth soaked in plaster, and 250 lbs. of plaster and bondo. The plaster is easy to shape and slight differences from one side to the other cannot be noticed. It was then sprayed with black paint to highlight imperfections.
I called a flatbed truck and after spending 45 mins convincing the driver that he was not looking at a steel or fiberglass car, but a steel car with plaster fenders, he drove at 35 mph to a fiberglass shop. The shop built molds from the bucks, and then fenders from the molds. The fenders are 17 ft long and extend across the front to meet in the center as an apron.
There is a picture of the car on my facebook page - Dennis Gronan and while you're at it, like my trucks' facebook page at Power Wagon Santa.
Hope this helps.
