Man, I remember when it seemed like
everyone was jonesing for a set of these. I had the opportunity to buy the front one brand new for around $600, but decided against it.
@Chris had both front and rear, if'n I recall correctly. Seems like the front one created clearance issues for the Antirock sway bar he was using (or going to use). This was a lot of years ago, so my memory might be getting the details a little off.
Good luck with your search/purchase!
