most of the american rabbit cabs had power steering, its nice to have with the car but its something at the cost of ?1000 you can live without.
there are a few rumors that you can use a MK2 steering rack system, odd times on ebay they come up, i wouldnt like to fit one and besides you eat into your engines power. Hell who needs ABS, Power steering, cruise control, ESP them toys are for idle people who drive on rails. The thinking mans car has non of these luxuries half the fun.
