Side mirrors fasteners

[Emzdogz]

Hi, I live in a busy part of the city with narrow streets and I have no driveway, so gotta park in the street.
Driver side mirror has been smashed off before, and when I installed a replacement I lost one of the 3 screws, so it's been hanging on by just 2 screws (car is a 2005 ZX4)
Has been ok that way, but the mirror got smashed off again last night. Sigh.....
I'm hoping at least the 2 screws I used are still in there, but I'm wondering where I could get a new set of all 3 fasteners.
Am I going to have to go to a Ford dealership for this?
Was considering taking the passenger side one apart and taking the fasteners to a hardware place and trying to match up usable replacements.
Any ideas for me? Where to get those 3 fasteners that hold the side mirrors on....
Thanks a bunch in advance!

A Focus is a narrow vehicle to begin with, I don't know how people are busting your mirror off. I would think that your neighbors are having the same problem. How close/far from the curb are you? I suppose you can get the screws/bolts from the dealer or a hardware store, or you can go to a wrecking yard if there are any in your area.
