Default POI adjustment

Is it possible to change POI by changing stock dimensions? I have a LC smith that I just got back from a total restoration and patterned it. At 30 yards it is shooting high, 90 % of the pattern is above center. Even worse it is about 6" left of center. This is both barrels several patterning shots. I compare this to my 16ga parker which patterns beautifully , centered, 50/50 distribution above/ below. The guns have similar stock dimensions, though I'm not really sure how to measure cast.

I'm not sure if this could have something to do with it, but after shooting the smith I saw that it was off face. I could see daylight between the barrels and breech balls and it was very loose with side to side movement with the forearm removed. Yet it seemed like the right barrel was further away than the left, and in fact I could slip a piece of paper in there with the barrels closed where I could not do that on the left barrel. Two sheets of paper over the pin tightened things up. Both barrels seemed to be tight to the breech. No movement with the forend off.

This is going back to get rejoined, but I'm hoping I can get his gun to pattern better.
