Call someone. I deleted my first post because I didn't see the pic. That looks like the torsion type that rests against the bulkhead of the garage. Very tricky and final adjustment is key. IMHO it is worth the money to have a professional installer come out. There are some jobs that you just can't beat a tradesman's cost.
