Probably not an easy repair. Could you use a thin shim to keep the springs and driver pins in the body, with the key pins in the bible? May need to have the bible at the right angle and most of the way pushed home. If the springs aren't too strong, it may just work. - doubt you can break it much more.
Alternatively, drill out the plugs in the body and tap the holes for grub screws, then you can repin it easily.
Why are lots of quakes reported in this little area? Is it an artefact of the algorithm or detectors, or a geological fault, or what?
