I have the same problem, my ES plastics arrived last night and I realize it when I opened the bag. I did find a link on line with directions on how to install these and where to buy the parts and tools.

You can find the information at this link:

With that said, Does anyone in the metro area in Michigan have the tools to do this? I would rather pay someone local to do mine then order all the parts for a couple of plastics. EM me if you have the tools and are interested in doing this work, I will pay you for your time.

Thanks !
