From the questions I see, it seems that not many people actually understand stamping large body panels. Yes, small parts can be made by many manufacturers as the machines required to make the parts are relatively a modest size. I used to work in an automotive stamping plant. The presses required to stamp out large body panels (floors, roofs, hoods, fenders, quarters) are GIGANTIC presses. And depending on the complexity of the part, require several of these GIANTS in a row to get the final trimmed, finished piece. The OEM's have these stamping plants. The shops that are capable of this for the aftermarket are far & few between. And believe me, NPD, Year One, Mustangs Unlimited and whoever else you can think of don't have their own.
