Thanks for the info here. I need same info. Anyone have pics to add?

Anyone have any photos to add to all the internet researchers like me out here who view these threads and benefit?
Thanks. Seems straight forward enough but photos sure help a lot!
Special tool list and sizes are a good help too.
Thanks~~~
