The LCA ball joint is replaceable. Off the top of my head i know MOOG makes a replacement lower ball joint. As far as struts. The new Bilsteins are adjustable for lift but the lowest setting add 3/4 inches of lift. So that means your front end would sit 3/4 of an inch higher than it does currently. I used the regular bilstein struts a while back and thought they were horrible. They blew out within 6 months if I recall correctly. I'm on 2 years now with my OME struts.
