After admiring the rest of the bits from GEARTRONICS I got started at mounting the actuator. There was only one really sensible mounting point for the actuator, as it need to be hard mounted to the box, as any flex may cause issue. Therefore, as the engine is hard mounted to the cradle, and there should be little flex here, I decided to mount the actuator to the cradle, as mountings for the actuator on the engine itself were few and far between. There are some obviously, but this way is far simpler. I may have to eat my hat there so, we shall see!
Firstly I had to modify the standard Hayabusa gear shift arm. This has pressed into it a link that was no good for me as it had a funny thread. Either that or mine was damaged. So i ground the back off, and then punched out the link. This allowed me then to insert a helicoil, so I could bolt the actuator to the arm. Unfortunatly I forgot to take any pics of this.
I cut out, very roughly, the below shape from an offcut of sheet steel we had lying around. Its a couple of mm thick so thats no issue and I have two so its not going anywhere!
I angled the top to suit the angle of the actuator, as in the pic below. On the ‘back’ plate Iblobbed on a captive nut to stop last minute panics with nuts and bolts if it ever has to come off. It shouldnt have to, but you never know with racing, and if you can make it easier to reassemble something in a panic for no extra cost/weight then its almost always worth doing!

So after welding on both plates here it is. It sits at an angle to the direction of the car, so as to fit! The gear shifting arm is as close to 90 degrees as possible, but again we shall have to see if it need further modification in the future.
