Unfortunately, I don't think that saas make boss kits any more. Although, if you want to get the steering wheel closer to you you could use an ordinary boss kit to do the job. I am lucky as I have access to lots of different CNC lathes and machines so modifing the wheel is no probs for me. But I did have to weld the 3 spokes of the wheel together and weld fill all the holes before machining the centre out to fit the wheel to the boss. It sits perfect for my 120Y. Around the same distance as the origional big wheel. I don't have any pics of it yet as it is still not finished but when it is I will post some up. The wheel only gets worked on in spare time but work is bloody hectic at the mo so it is at a standstill unfortunately.
