It was a long while ago now since I posted this, I did look one year at W & P Show, a brake servo which I think was for a Ferret, it was on a dealers stand, NOS, and thought that could fit a CCKW, but after taking advice, was told it probaly would not suitable, although since then I did wonder if this was correct, has anyone out there fitted a Ferret servo to a CCKW?, or even tried and found for whatever reasons it was a no go?
