Do not know what they are called, but on the rear bar attach to the to the correct side. Seach, I think there is a good write up on how some one installed them. They are awesome.

The only issue I had is removing the bolts that connect the bar to the bar ends. The bolts had rusted and it took us a while to remove. We in fact removed the bar ends and then got them off the bar on the work bench.<ul><li><a href="http://www.h-sport.com/bin/instructions/22816.pdf">http://www.h-sport.com/bin/instructions/22816.pdf</a</li></ul>

WOW!!!!!!!!! What a difference they make. Hard setting doesn't seem harsh at all so I will leave it. I should have done it months ago.
