I just had the rear shocks done on my 2001 SLE. I went with the advice of other post and went with the Delcos. They came with the shock mounts on them right out of the box. They were only about $30 more than just getting shocks. The monroes did not come with mounts and would of cost almost double when buying shocks and mounts seperately. I know most of you guys probally know this already but, what the hell. I had a shop do mine for me. But after watching the install, I wish I did it. They were done in under an hour. Looked very easy. He charged me $193.04 for the shocks and $70 for the install. The whole job came out to $285.73.
GM parts direct list them at $177.69. There price $88.85. Ship for $21.32. Total $116.39. I could of saved $169.34, if I did it myself. I saved the box flap. It reads, ABSORBER, GM # 22064810.
Good Luck. Hope this helps someone.

Okay yeah, thanks for the info. I may be looking into doing my rears in the near future.
