Independance Air Questions

I have been repainting POSKY's CRJ-200 in the colors of Independance Air. I have the plane completed except for the strip on the back of the livery. I cannot get the band to line up with each other. Is there an easy way to line up the two halves? Also, how can I place the dots on the back so they look correct? There is a picture at http://www.flyi.com/com-planes.htm.
