I have that wheel. I'll try and get you a pic sometime soon. As far as I remember it was quite easy to fit - do you have a pic of the bits maybe I could point you in the right direction without having to drive to the garage with tools.
It's for sale if anyone is interested - complete with boss for Mk4 Escort. Condition is good but used. Some scratches but no stitchin falling apart or anything. This ist the best wheel I've ever had in a car - they are really nice. Lovely leather and great design.
