weber carb (HELP)

Hi just fitted a weber 32 34 dmtl to my 1800 cabby mk1 which also has a k&n to be fitted to it.I am struggling to find out where all the vaccuum pipes go including the distributer and the servo pipe.
The engine has been replaced by a numpty then i bought it and i am trying to get it sorted out and running perfect the radiator has a reservoir built in instead of a seperate one and all the metal coolant piping has been cut and made to fit which means that there is no correct circulation which means i am stuck with the inlet manifold water pipe unconnected so if any one can help with info and pics of this part of engine to help me on my way thank you June
