You should do it then. Adjusting the switch position is easy and shouldn't take more than an hour or two.
The GM procedure for adjusting the switch is at the bottom.
I start in the engine compartment by releasing the transmission gear select connecting rod from the crank arm on the intermediate shaft.
Back in the cab, the lower column trim cover and dash filler plate come off:

With those removed, you'll be looking at this - except your bezel and IP will still be there:

Don't forget to release the clip on the end of the gear indicator wire:

From where it clips to the bowl shroud:

Then just release the two nuts that secure the column bracket to the instrument panel support:

Lower the column until the steering wheel rests on the seat and adjust the switch as necessary.
Removal procedure per GM:
1. Disconnect battery ground cable.
2. Disconnect and lower steering column. Only lower steering column a sufficient distance to perform ignition switch service.
3. Rotate ignition lock to the OFF "locked" position.
4. If lock cylinder has been removed, pull the switch actuator rod up to stop, then down
to the first detent position as shown, Fig. 7.

5. Remove column mounted dimmer switch, if equipped, then remove switch retaining
screws and switch.
Reverse procedure to install, noting the following:
1. Place gear shift lever in neutral.
2. Place lock cylinder and ignition switch in positions noted in step 3 & 4 above.
3. Fit actuator rod into hole in switch slider and secure switch with retaining screws,
ensuring switch does not move out of detent.
4. Install and adjust dimmer switch, if equipped
5. Torque retaining screws to 35 lb in, then check switch operation.
Those are probably the worst instructions I have seen in a while.
Anyway, since I was looking at doing this job soon myself, I checked which way the rod moves - in relation to the rotational direction of the lock cylinder.
If rotated CW (START) the rod moves toward the switch. And if rotated CCW...
