HELP! Passenger rear caliper piston will not compress
So today I was changing out my brake pads and rotors. Fronts went smooth. Rears were frozen, but the drivers side went smooth. Now, when I got to the passenger side and tried to compress the piston by adjusting the HEX key in the back, they key just kept turning endlessly, and piston never moved. So I figured, might be easier after I dissamble the whole unit, so I removed the caliped, rotor, pads then tried doing it. Now I realize that the HEX piece was so loose, it FELL OUT! Now I'm stuck with a car with no pad or rotor on the passenger side. Any one have any ideas on how to compress that piston so I can install the new pads? Tried searching, got no luck. Also wanted to try to use a C-clamp and push the piston all the way back, but then read this article and didn't http://www.miata.net/garage/brakepad.html
Any ideas?
Thanks in advance,

If the piston won't retract or extend using the hex screw, usually something is seized or a gear is broken. You can try applying a small amount of pressure on the piston as you adjust the pin to see if that works. Otherwise you can get a refurbished caliper fairly cheaply, or if you are up to a challenge, you can get a rebuild kit and rebuild it yourself.
Here are the internals, by the way:
