If its a rear you're looking for, I have one on my car, and this what you need:
the bar, 2 endlinks, 2 (one on each side) bolt/nut to attach each endlink to each LCA, 2 rubber bushings that the bar sit in, 2 little metal loops to hold the bushing & bar to the brackets, 4 ( 2 on each side ) nut/bolts to hold onto the loops, 2 brackets that hold the bushing/bar onto the car, and 4 (again, 2 on each side) nut/bolts to hold the brackets onto the car.
if you got all those parts from Honda, I have the actual part sheet and I think the list for all parts total is like $240. Do yourself a favor and get one used...I got mine for $80 for the entire setup.
