First of all, get the KE70 column, and slide it onto the top half of the KE70 uni joint. Then, you will find the bottom half of the uni joint is still connected to it and fits well. Then get the bottom half of the uni joint and slide in onto the pinion splines of the KE70 pinion. Screw the pinion into the KE70 rack housing. Then the rack may fit onto the KE70 crossmember. With 4 long bolts the KE70 crossmember bolts to the frame.
