Just followed that link - great site, very well written and photographed how-to.
Very cheap as well, now I'm considering cruise as well. Only thing that bothers me is f*cking with the steering wheel, due to two fears:
1) don't fancy setting the airbag off
2) what happens if I can't get the b*stard back together!?
Car goes in for its 40K mile service at Vindis in two weeks, so I'll ask them what they'll charge to fit it all.
Just goes to show you what a rip off options are at the time of purchase eh? That's prob a ?300 option at the time of build, and we can can buy the parts retail for under ?60!!!
