No, Jim. Good question. The armor is slightly concave/convex. With sintra, it seems as though most here have heated the piece in a pot of hot water, and shaped it on themselves while wearing a t-shirt(oddly enough, they say the sintra won't burn you).
Try looking around for a suitable printable set of blueprints and adjust them to your size/frame. The reference CD is the best source for the proper "look", and can be found in Secol Fett's signature here on the board.
None of this stuff is for sale, obviously.
