767 and 747 Rolls Royce engines are exactly the same except for three parts, none of which you would be able to see with the engine fitted to the strut.
The front bit, called a nose cowl, on the V-Pod is a normal nose cowl. There is a cover that is placed on the leading edge of the nose cowl for aerodynamic purposes.
The next cowls back are called fan cowls and are also only used for the V-Pod, but they are essentially the same as the others on the aircraft. The cowl behind that is called the INA (Integrated Nozzle Assembly) and is part of the engine itself.
The strut, the bit that attaches the engine to the wing is only used for the V-Pod. If you look at Michael Mak's photos there is a picture of the fittings in the wing where they attach the rear of the strut. The front is attached to the leading edge spar via a "banana link"
The fan blades are removed and a "bung" is placed in the inlet. This prevents the engine from turning the entire time it is in the air. A small amount of air is allowed to pass through the core of the engine, but not much due to the "bung". The blades travel in individual boxes in the hold of the aircraft.
Hope this helps.
