The azz sag is do to either a large system or bad rear struts. Get a good suspension kit (Bat, etc), the azz sag will go away and the car will either be level or a bit raked. Instllation all depends on where you go. Peopel have said they've gotten install quotes from places liek midas (why) for 600.00 and mom and pop places fro around 200. A better bet would be to post a "help me out" topic in your "area". Might beable to get some CEG'ers to help out. Lots of us just work for food, good music, booze, etc.
