Hi Les
I am aware that Speedies, amongst others, sell webers carbs for our commers. However, according to the people that make them, i.e. Weber - there is no direct replacement offered, meaning that what's being sold would be an approximation for the engine rather than a carb that's been jetted correctly for the engine via a rolling road - unless Speedies have invested in this themselves and order carbs based on those findings. The suggested jet sizes I was quoted were for a Land Rover.
