Front or rear? The Energy Supsension end links are good for the rear sway bar. They are MUCH better than the OEM crap. I got the longest size they had, and it was an exact match for the Taurus. For the fronts, I would go with the Moog brand end links, or stock end links for a newer Taurus/Sable or Windstar. Universal end links won't fit (just look at the end links on your car, and you'll see what I mean.) For the rear bar bushings, the Energy Supsension parts wont fit properly. Your best bet is to get bushings from
SHO NUT Performance. As far as sizes go, I'm not sure what the thickness on the SLO would be, but I'm guessing 21mm front, 19mm rear.
