This is just a guess, but from looking at the somewhat flimsy support under the rear shelf in my 97 I would guess Ford had to add reinforcements for the mounting of the top wind up mechanism. Unless you did a side by side comparison and saw that the parcel shelf undersides were identical, I wouldn't risk it.
