there has been a couple of shots of connection points. Primarilary to the steering head, either with a clamp, welded or bolted. I know this is not a popular choice, as it requires drilling and tapping and some probably more advanced machining, but this is what I did on the 950. The reason it has so many drilled and tapped holes for bolting things to is because when I started I had no idea what I was going to make as the 'nav-tower' so I figured the more attachement points I had at my disposal the better. The ali Block is held onto the steering head with Sikaflex and 5 off M5x0.8 CSK SHCS. It has proven to be very reliable, having survived some big crashes that destroyed the tower.
