here is something to mention, if you use s13 balljoints with these they come with a tapered insert for them to fit in the knuckle. if you try removing your flcas, this might get stuck in them.
I had one side come out, the other size wouldn't budge. I had to cut the ball joint off of the flca, and hammer the insert out with a socket. I tried to just knock it off with a hammer, chisel, pb oil, and other things but I didn't want to ruin the insert, and since I was replacing the lcas anyways it didnt matter.
Here is the insert I was talking about stuck on my lca, this lca was replaced within the last few months, I was just switching them out for extended ones, and I installed the kit 2 weeks ago and never drove on it, so rust or old parts wasn't the issue.
