I am building a new patio/sunroom, and I have framed up a small shear wall, along with openings for 2 new 4x6 windows. As I tried to install the windows today, I realize that the openings are out of square. One opening is not allowing the top of the window to sit into the opening by 1/8 inch, and I don't have enough slack on the other side to bring it up.

The other opening next to it, is out of square too far to one side. So I will need to put in more than shims to make it attach.

Any practical suggestions?

Thanks for your help.
