The blue GT500 is 1653.
Here is the original road test picture for that car. I identified it by this decal and a few other items.
Tim says the height of the decklid face is 5 7/8" at the end cap seam. You can see the decal takes up most of that space.

The cells for the tailights are 3.5 (wide) x 4.0 (tall) That should get you in the ball park. Not sure if its white or silver, I would go with a silver and not chrome.
I think probably 4 inches is a good guess for height. I opened this picture in paint and you can show grid squares and see how they compare to the taillight cells.
I see a little more above the decal and less below (like 3/4" below and 1 1/8" above)
