Rob,
I had the same problem.
What I did was to measure the amount of interference between the anti roll bar drop link & the track rod link arm the make some spacers accordingly & add 5mm. These spacers shuold differ in length from N/S to O/S, although I cannot remember what these measurements were.
Then, disassemble the stering rack ends,fit the spacers & reassemble. You will notice that you have limited turning circle so I would suggest that you remove these once through the MOT. Paul Thompson is correct in saying that the original Ford donor vehicle has this characteristic of the anti roll bar drop link hitting the upright, but this doesn't cut any ice with the SVA inspectorate!!
Hope this helps.
