You could follow what Rick says, or consider the facts.
A DYE to stamp a ford wing will be in the region of £100K, now ask how long it will take any company that would buy a die for this to recover their cost.
The answer is they won't, the supply of pattern panels is almost always done on EX Ford dyes, or whoever makes them for ford.
The dyes do not last indefinitely, the tolerances go out due to wear, the old dyes are sold to pattern people, as prohibitive cost to make for such low volume stuff.
Having had £2.5K of bodywork done, I have NO complaints whatsoever about hadrian wings etc, the only bit I didn't like was the bonnet, as the frame was not bonded to the outer and so flexes.
