Just came across this wonderful post to the Canon 5D MarkII - Parts Catalog from the excellent forum 5DMarkII Team and would like to share with you.
Here is the direct link to the post that I'm sure you will find very useful.
If you are having trouble downloading it from there I've created MediaFire direct links to help out the downtime server issues.
I'm also including a direct link to the 5D MarkII Instructions Manual PDF just in case you did not get it in English.
