ok so in answer to my own question

after some research am I right in thinking I need.....
mk3 Alternator, mk3 power steering pump, mk3 belts, a different pulley for the water pump, (the one that sits the other way round) and the additional pulley for the crankcase sprocket.
But.........if I use a mk3 power steering pump, can I use my original reservoir and lines that attach to the pump?
