The RS MTX75 box, and i have box's full of shafts so was using either the 2.0 standard shafts or the TDCI diesel shafts,

Non of the focus shafts including the st170 use the smaller bearing like the RS or have the same size bearing cups!

I know that the mk3 mondeo diesel use the same shafts as the RS although they will be too long just like the FRS shafts are for the standard focus track!
