Sounds like you have a stock suspension? You shouldn't have any trouble locating all of the parts and pieces over-the-counter, either from the dealer or on-line (think Rock Auto). I just had some of my front end re-done and had to get certain parts from Quigley (since I have a converted 4x4) and for others - Quigley supplied the Moog stock numbers and I sourced through Rock Auto. Sounds like Moog is a reputable supplier of front end parts and pieces...
