Have (4) 2ft x 16ft2inch steel garage door panels, spring, horizontal and vertical roller guides.  Would make a 8 ft tall x 16ft2inch wide door as-is. Vertical and horizontal roller guides are for a 12 ft tall door but could be cut down to work for 8 ft.  Or add two more panels and youd have a 12x16 door.  One of the panels does have a slight imperfection, as shown in pictures.  OBO
