To extend the to hook I used a coupling nut and bolt. Unfortunately Ace didn't stock a 12x1.5mm coupling nut and quite frankly I think this is my first encounter with a 12x1.5mm anything. Luckily they did stock 12x1.5mm nuts, so I welded 3 together and made my own damn coupling nut. I also ended up using a longer bolt than pictured once I decided to add that piece of flat steel to the beam.
