Honestly, this is probably not 100% legal. It looks like this guy d/l them from the site and is trying to sell what he d/l.

I would recommend that you just cough up the $20 for the one day subscription and d/l them directly from Nissan. I did and was able to get them for my Maxima also. Ended up being pretty convienent but took a bit to d/l all the parts.
