Iv seen a mate of mine make one , and im considering it myself , he got a clutch pedal mecanism out of a scania lorry , ( actual pedal cut off ) and then connected that to his hydralic clydinder , which he got of a man who does tractor parts , then once it leaves the cab im not sure how he connected it but you've already been told that, anyways just said id tell you so you can consider , they are a massove improvement and well worth any hassle they may cause in my opinion !
