2001 Qx4 - need help with...

[QxMan01]

finding part numbers for the rear lower control arms. As I mentioned in a previous post, I have the death sway going on and have decided to purchase the control arms from infinitipartsusa.com (Infiniti of Scottsdale I believe). They have a lot of choices even for the particular year and car, so I need the specific part numbers for the left and right rear lower control arms for a 4wd 2001 Qx4. Any help on this matter is greatly appreciated; I am trying to rectify this situation ASAP (for safeties sake of course). Thanks in advance!
