I had the hand controls fitted last Tuesday, they are 'Jeff Gosling' controls rather than the 'Alfred Bekker' ones I had expected, but I am very satisfied with them - a very tidy job. I have a single handle just below the steering wheel - pull it up to accelerate and push it down to brake. It felt a bit strange after over 50 years of driving using foot pedals, but I am getting the hang of it and I am more confident each time I go out.
I phoned my Insurance Company and told them, but they advised me that they don't consider it to be a 'modification' and so my premium will not be increased. The best bit is that my wife can still drive the car using the pedals and is not put off by the manual handle moving up and down as she moves from accelerator to brake. The cruise control feature of the car, which I use a lot is, thankfully, unaffected by the new controls. The controls were fitted, at my house, by 'Ace Car Conversions'. Here is a picture of the new control :-
I am a very happy bunny as I will now be able to drive long distances. I had thought that I might have to give up driving, which I would have found very difficult. My thanks to UncleZen on this forum for his encouragement.
