Mazda 626 Outside Mirror replacement

Anyone tell me how to remove a broken outside drivers side mirror. I have a replacement mirror in hand but am unclear as to how to remove the broken one

hi, this can be a pain but you have to take off the corner thingy on the inside of the car near the mirror. You should see three bolts you have to take off and everything is pretty easy to figure out from there. Except for mine one of the bolts was stripped so i had to pretty much hammer my mirror off. Worked out okay though haha. good luck
