`Cuda Gills...What do you think

Hey, what about using cardboard as a template for the tail lights?? I like what norshor did with his pics. Not sure in those pics if I like 3 or 4 gills, for me I would go with whatever is gonna look good and mess with peoples minds!
Great idea with the cardboard! Anybody got some specs on how far the spacing is between the "ribs" are on the tail lights?
