hello folks. just got myself a pao and starting to sort bits out. im trying to fit a manual steering rack and have got a bit stuck. the splined shaft on the end of the uj attached to the rack is too small (15mm diam) for the splined hole in the uj on the steering column (17.5mm diam). the rack is off a k reg micra k10. does anyone know if another part will fit? cheers in advance.... karl.
