I fitted a Dia-Compe one to my Fort recently. Bought from TFG and works great. One recommendation I would make (I think I got it form another thread on here) is to put masking tape or similar on your forks before installing the clamps. They are exceedingly frustrating to get on and the tape saves the paintwork form scratches. Once the clamps are on its simple to get the tape off.
