I bought mine at Shox.com
I ordered the 1 1/4 bar. it comes complete with Poly-bushings, link pins and all.
Here is the part number from Shox.com for the Addco 1 1/4 rear swaybar I bought in Aug/04
part # 632U
description: *DS ADDCO SWAYBAR 1 1/4
I paid $159. there was $24 freight, and I had to pay sales tax(calif)
The bar comes complete with poly bushings, end links, and all neccesary hardware. You MUST retain your old stock U-clip bolts, and shim them with washers to properly mount the new, thicker bar.
if your car is lowered, tell them when you order it, and they will send the proper end links for a lowered car(funny, they dont ask though)
My car is lowered 1.5 inches, and I used the stock height end link kit without any problems.
