Very easily. However keep in mind the bushings are shot, and need to be replaced at this point.

Apply parking brake, then loosen swivel nut, Fig. 8.
Place column selector lever in neutral.
Place transmission in Neutral by moving shift lever to its forward position, then back to the second detent position.
Holding shift rod tightly in the swivel, tighten swivel nut to specifications.
Place column selector lever into park position and check adjustment. The column selector lever must move through all the detents. The engine must start in the park or Neutral positions. With the selector lever in the park position, the parking pawl should freely engage within the rear (reaction) internal gear lugs or the output ring gear lugs and prevent the vehicle from rolling, which could result in personal injury.
