Ah, yes I forgot about the spring compresion tool that you need. I rented one from another member whose name escapes me at the moment (you might find him by doing a search for spring compresser tool or the like - I know he's in TX). You can probably also rent it from a good tool rental agency or even buy one if you have the $$. With the correct tool, its a rather easy process...I do have some hints I can share when you get closer to the project and I have some more time.
If you want a really good description of the entire process, I believe Mike Tangas posted a lengthy thread under the title of 560SEL accomplishments or something similar. It was Mike's thread that I used as a guide - along with some additional email back and forth from him directly - when I did the entire project.
If you can't find the information in the archives here, let me know and I can dig thorough my files for the necessary information.
