You will need a mondeo or 2.0 focus half shaft on the o/s then custom ones from that to the hub and on the n/s aswell because there isnt any factory shafts with the correct spline and lengths that work.i mocked up one for the o/s ages ago and it was about 3inches shorter than standard and had to have mondeo spline on the inner so the inner cv joint fitted and fiesta outer spline for the outer cv joint and the n/s shaft was about 1 inch shorter than the o/s one with the same ends as the offside one
