Help! How to remove a bolt for replacing passenger mirror

[google_seller]

Hi! I am trying to replacing the passenger mirror for my Camry LE 2003. I am finding I have troubles removing the old broken mirror. The problem is that I cannot unsrew the third bolt after taking off the other two. There has so little room for my 10mm wrench, so I am wondering if anyone can help me which tool I need to use or which part I need to take off first. Thanks a lot for your help!
