Can anyone tell me what size tap I need to get for the studs that hold the valve cover and the water hopper cover onto the top of the cylinder head of the D-type?
An online place where I can buy said tap would be good too! :)

Chris,
5/16 BSW (Whitworth)I pick up all my old taps and dies at Rallies, but I am sure someone will sell them online.
Regards.
