Hi first time here...I have a similar garage in which i would like to clean up and use as a pool table room. I am getting a new door installed with a new Jack opener which will eliminate the old style Genie which is attached from the center of my garage to the door. I am have a few 2 x 4s spanning from the back of garage to over the header of the garage door. There are 2 braces (1x6) that form an "X" if you look upwards. Does anyone know why these were used and can they be removed if i double up on the 2 x 4's mentioned above? I see that in Brandonlaundry's these are not used.
