Help with Addco Sway Bar

With that mount arrangement you will have to swap the spindles and calipers. With all stock parts you can shorten the end link and the bar will react quicker, but the location of the tabs is VERY critical or you risk shearing of the link. It's not a big deal to swap the spindles. Bear in mind that the factory disc brakes for your car had rear mounted calipers and did not interfere with the sway bar. The late cars with the front calipers used a narrower sway bar for clearance.
