Alignment is by using the the fastening holes, provided.....?

Scotty, I agree with Kent that this method would probably be your easiest and fastest method to achieve success. I have a photo sequence in my book SHEET METAL FAB for CAR BUILDERS showing Mark Gerisch using this method to make license plate lamp indentations on a 427 Cobra boot. He uses 1/2 Bondo and 1/2 "cat's hair" Bondo to make the dies, but Kent's suggestion of Devcon is what I'd recommend as it is much stronger.
