Here's some interesting info on the Opel Corsa EPAS units:

The Opel EPAS motor is no larger than the one EZ Electric uses. I believe you could only use the EPAS motor and load sensor. The control unit could be mounted remotely. You would need to fabricate a new upper portion ("input"), between the EPAS motor and the steering wheel, as well as a new "output". That's how EZ Electric makes an almost bolt-in kit. Everything in front of the EPAS motor is fabricated by them, as is the output.
