Guys on Ebay at the minute the popular Escort MK1/2 or Capri/Cortina Corsa "C" Electric Power Steering Unit as used on UK and Irish Race and Rally Cars.
This is complete with the correct ECU and Controller to suit this model. You just need to use your original Steering Column, Boss and Steering Wheel and off you go.

Also still available at the cheapest price anywhere, the popular Escort MK1 Standard and Twin Cam Guards. (These are even cheaper than the UK retailers as I buy them direct from the Irish manufacturer who owns the tools and dies. The UK distributor only own the distribution rights.)
