I used the 2-3 thread rule and locktite on the old nuts.

Who knows? Unless we know the running torque of the locknuts they used when the wrote the instructions, and use the exact same locknut, the resulting amount of compression probably won't be what they intended, and what they intended may not be right anyway. As I recall, the instructions don't specify, and there may still be variation between brands. And as you probably know, the metal ones are one-time use, and some people don't know that and will try to re-use them, so then the amount of compression would be different then too.
This is why using nut torque to compress the mounts is ridiculous; the results will be very inconsistent. 2 threads above the nuts on the original length bolts is pretty consistent, with only slight variation due to nut height.
