Now to fix this follow the service manual instructions and remove the camera back and bellows. You do not have to disconnect the body release cable at the body. Run the yoke out to its limit, slide the front standard to the front of the yoke and lock. Remove the screws from the case guides then gently pry them up off the pins keeping the shims for each side separate from the other. Turn the guides 180° and reinstall on the pins on the opposite side of the case then install the shims on their correct sides then secure with the screws. Run the yoke in and out full travel of the case section of the yoke to verify correct alignment. Reposition the shims as needed if the case guides are not in proper alignment. Once correct reinstall the bellows and back.
