Sway bar linkage

That's true, and a good reason to get rid of the end link/bushing set up that was on the car previously.

But realistically you're only talking about ~2.5" of travel in each direction, so it's not like you need to have something anywhere near as tall as the factory end links to cover the divergence in the arcs. It’s not that much in that relatively short distance.

This is the set up that I’ve been running for years and tens of thousands of miles, it doesn’t bind up the LCA and those are poly bushings. Obviously you don’t want to interfere with the motion of the LCA, but the more “give” that you have in the bushings and end links the less active your sway bar will be. There are tons of heim jointed sway bar end links out there.

Not disagreeing... a short link with the ends free to move is all that is required. It was the set-up pictured, with zero free length and the bushings squashed, that prompted my dissertation. Actually, your solution looks a lot like mine — I used heim joints instead of bushings, trying to adapt a somewhat poor fitting Addco sway bar.
