Man that poor garage. It has smacked bike racks, been half fixed many times before I installed a Wayne Dalton garage door opener, that somehow got me 34K youtube hits by opening and closing it.
A recent incident knocked the track off a bit and it broke yhr door bad. I tried bigger screws, and it worked for a few days. To get this back to proper working order I needed to bust out the sawzall, a tube of PL400, many strips of wood, a chunk of wood, and more drywall screws than I care to admit. Once the adhesive settles all will be good.
