Independance Air Questions

[daylightla]

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.
