There are two rods that move the levers on the transmission. Both have threaded sleeves to adjust the length. Disconnect the adjustable end of each rod, and with both the trans levers and the levers on the column in the neutral position, the rods are length-adjusted so they line up with the appropriate holes in the levers. With worn or disintegrated bushings it's kind of a waste of time as you can't get any accuracy. One rod adjusts at the column and the other adjusts at the trans. I believe the rotating collar on the end of the column tightens up the clearance through the shifter gate.
Of course i was busy last night and forgot to look for them.
