We did use the mk5 setup but modified it obviously to fit. The brackets and mounts have been sourced from the Escort RS2000 and the pump and drive parts have been fabricated from another car

. The old steering rack needs to be removed and the securing brackets need to be taken off the bulkhead to make room for the other brackets from a MK5/6. The height of the rack is the most important part cos if its to high turning is shite with big wheels or fast speed.
I have all the pictures from the car i think a few are on the site
