Shop the "take-off" sellers for complete sets of GT sway ("stabilizer") bars, including the brackets, but not the nuts/bolts/washers. The nylon-lock nuts are labeled "single-use" in the shop manual. Many here and elsewhere have re-used the nuts ; the warning is more a corporate liability CYA than a practical necessity, in some folks' view.
I got the bar/bracket/bushing f&r set for under a hundred dollars, delivered. I put the rear bar on first (needed some clip-bolts, not that easy to find) but otherwise a straightforward install that made the V6 nearly a neutral-steerer. Very nice, ran it that way for a couple months, then ...
TODAY, swapped out the V6 front bar for the GT one. AMAZING! It transforms the car from a nice boulevard cruiser to a quick, fast cornerer that instills confidence in high- and low-speed turns, with no influence on ride quality.
Mr Ford should make this setup standard on all his sporty vehicles.
I'm not to the point where I can say if it's close enough to neutral steer or if it will need a bit stiffer rear bar. We shall see.
Meanwhile, if you have a V6 and haven't upgraded to the GT f&r stabilizer bars, you don't know what you are missing. Transforms the car, it does.
