LOL There isn't a redesign the suspension anywhere in any of this.
The brakes are the issue.
Every bar that goes around the early K ( cant go through like later A ) will be pretty much the same and will work just fine with the OEM brakes
The problem here is the brakes were changed to late A before attempting to install the early A sway bar.
The late A sway bar would bolt right on too no matter what brand but only with a late a K that allows the bar to pass through.
