Maybe I'm doing it wrong, but I have the special tools and never use them.
1. with the drive off, adjust the brass barrel on the lower shift cable so that the shift cable end sticks out of the bell housing 7/8" to the bottom of the ball end and temporarily secure the cable on the shift plate on the engine.
2. install the drive
3. remove the cable from the shift plate on the engine.
4. ensure the drive is in neutral,
5. ensure the shifter/throttle is in neutral
6. adjust the brass barrel on the lower shift cable until the cable installs loosely onto the stud and barrel bosses on the shift plate.
7. Temporarily secure the cable in place (don't bend the cotter pin yet and don't snug the nylock nut down yet)
8. Test with engine running, if shifting is good, properly secure the cable on the shift plate.
