Change of direction - after offering the EPAS unit in the foot well, I've come to a critical realisation. The bloody thing won't fit.
Well, actual it could be made to fit, by dropping it so low almost interferes with the pedals - or by re-arranging quite a bit of stuff under the dash - but to be honest, it's just a hell of a lot of work for very minimal gain.
I'd measured all of this before I started turning all the bits and started mucking about the second BMW column I had and the corsa column... But it's only after really trying to shoehorn it in that I've realised it's not really going to work.
So, no power steering for Vikki.
Anyone want a corsa EPAS column to play with?
