not so much the LCA, but the ball joints attached to them. Ball joints are like 30-35, the whole control arm is like 45. Then you also get the new bushings and dont have to drill out rivets.
Check rockauto again, they were the moogs. You will probably need an alignment if you do those... but not positive. If you have to, change the tie rod ends too.
