Wilwood brake kit - too close to steering arm?

Hi Guys, I've just fitted a 260mm vented Wilwood Midilite Brake kit.  These are the commonly sold kits from the UK from places like Burton etc. The new thicker disc sits very close to the steering rod end, in fact the rubber boot is juuust touching the disc.  Has anyone else fitted this kit and had similar problems?  It's in a Mk1 but I believe the previous owner installed mk2 steering rack. Any suggestions appreciated!

This is a major criticism I have of a lot of brake kits out there for the Escorts and is why I went down the road of creating an alternative option with the RX7 calipers and Pug 283mm rotor.
Even the Hi Spec kits are VERY close (1-2mm) to the steering arm so I will probably use an alsternative disc to provide at least 5mm clearance.
I often wonder why such basic engineering principles (ample clearance) are ignored when producing replacement items such as this and I doubt my engineer would let it go.
That being said, I would assume the Capri strut with the seperate steering arm would be the intended recipient of these kits although they do "fit" the Escort strut.

I thought the UK guys only got the capri/rs struts, so you could space the steering arm out?
And I am sure I have rear somewhere here that brand new tie rods have smalller dust boots?
