I guess the arnnworx tool is for a late model - mine is an early and I don't remember using any special tools. Wasn't really that hard of a job.

Regarding the torque wrench issue. Instead of getting a large t wrench I just had to stand on the ratchet the correct distance from the nut. In other words, if your weight is 200 pounds and you stand 2 feet out you've got 400 foot-pounds. Or, if you're 164 pounds you would stand 2.43 feet (29.2 inches) out. No need to buy a wrench for one job.
