I also removed the 7' door and put in an 8' to fit my LSV in the garage. It cost me around $1500 for the new door, opener, and framing materials. Unfortunately for me, the existing header was directly above the door and not right to the top plate, so I had to move the actual header. Also, wind bracing requirements have changed so I had to do a portal frame. I was able to sell the old door and opener for around $300
