i am thinking of fitting a servo to my series 1963 2/3, and looking at my 1974 carawagon this has a servo fitted, so i am asuming that servo's were fitted to all LWB series land rovers and if so would one fit on my series 2?.
You don't mention whether or not it is a diesel or petrol, if it is a petrol you can tap straight into the inlet manifold for the vacuum hose but if it is a diesel you will have to use the latter system with a butterfly valve fitted to the inlet manifold or fit a belt driven brake vacuum pump.
If you need any pics of the two different type I will post later.
