USS Spruance DML

Just got the kit the other day and noticed a some flaws mostly minor till now. On the fantail the white lines marking out the MK 45 5" naval rifle concussion zone is badly off center. All views of this area on the model instruction sheet show the lines off center just like the actual casting. Having worked on Spruance personally, taking part in the removal of all the toxic and recycleable materials and sensitive equipment, I know this was not the case. The gangway was just behind the aft rifle when we were stripping her for sinking, so I know this is wrong having come to work everyday seeing the lines daily. However, DML's USS Kidd has the correct placement of these lines. I worked on all 4 Kidd's during the Tiawan conversion and know that the lines are centered on the gun. Does anyone know of an earlier configuration in which these lines were off center of the rifle? If so why ? The Kit is in the 1980's post VLS upgrade and the pictures from back then show the lines centered.
