When you make the shafts just use wood dowels for the setup. I used 3/4 in dowels for all the shafts. I can actually turn the wheels with them on the ground. I used a splined output on the rack and double D for the rest. Yes you can do the 'clocking' to get the steering wheel position close. Actually you can use one u-joint on each end and be ok. One end of each joint is fixed to a steering box or the column. If you use an intermediate shaft you need the support bearing. Make sure you drill a good spot for the set screw and lock it down. I paint marked each set screw as I tightened them so I wouldn't miss any.
