Need to Replace the Passenger Side Mirror Cover

[Devi8tor]

Someone sideswiped me and the cover to the passenger side rear view mirror got cracked. (mirror is fine). I ordered one from Mazda for $30.00 and it will be in a few days. Have looked everywhere online for instructions, any instructions on how to replace it. Anyone have any info or links that might help?
I would appreciate it!
Thanks
