I worked at night with an LED light. I had an extra mirror laying around that the base had cracked on (stupid non-folding mirrors) so I just ripped the mirror glass out and looked at that one to see where the clips were.
I cant seem to sleep tonight so I guess I'll go down to the garage and take a pic and make it a little easier for everyone. (hint hint I wouldnt mind some rep here at all!) hehehe...

Here's a few pics that should make this a piece of cake for you... These pics are of a drivers side mirror, just flip it for the passenger side. I'd recommend skipping your smallest flathead screw driver and just go for a longer one. I found it was much easier to bend the tabs with more leverage. Also, dont be afraid of breaking the tabs, they are made of fairly resilient plastic and can easily be bent back into place. (I've removed the caps several times now to get the polishing done to my liking)
1st a pic with no edits so you can clearly see the tabs...
In this pic I have circled the recessed holes where the tabs are, and also included some arrows that point in the direction the tab needs to be pushed with the screw driver... I found it easiest to start with the tab on the far left, then work clockwise to the tab on the top, then the tab on the right...
and finally a pic of the back of the mirror cap itself so you can see the tabs...
