Havnt looked at the T but on other cars I know there is a bolt and nut on top of the steering box. If you loosen the nut, then turn the bolt in a little bit while someone else wiggles the steering wheel, you can get rid of the slop. Then hold the bolt in place while you retightn the nut. If you dont hold the bolt from turning while you tighten the nut, you can overadjust and cause excessive wear or binding.
