Tech Note
You will need to remove the back cover from the camera body. If you look carefully at the hinge side of the back cover.
Many FR series cameras have a very small slotted screw attached to the hinge pin. That pin will retract if you push straight down on the screw with your fingernail and you can remove the back cover from the camera body.
If the small screw is not visible, you may be able to push down on the hinge pin with a tweezers point and remove the back cover from the camera body.
Use Caution….
as the hinge pin is spring loaded, you do not want to launch it across your room.
If you are unable to remove per the instructions above, you will have to remove the bottom cover, then the 2 screws that hold the lower hinge pin pivot in place.

Tech Note. CAUTION and do not be fooled
…by what appears to be an easy removal of the focusing screen retainer, which the mirror cushion attached to. Only 2 screws, Yes, but the focusing screen retainer plate holds the screen frame and screen spring in place also. It takes great care and practice to reassemble those pieces without damaging the Fresnel.
Mirror Cushion
Now, with the utmost care, install the mirror cushion. Center the cushion on the focusing screen retainer plate. This cushion is not intended to fit edge to edge of the mirror box sides like many mirror cushions. Remember if any thing touches the focus screen, it will likely be permanently damaged
The most important and time-consuming work is removing the old seals. Focus on clean, clean, clean. Clean the old residue from the door channels, mirror cushion area, door hinge area and anywhere else you are replacing the seals. The finest adhesive in the world will not adhere to that sticky, gooey residue that was once a quality light seal. Proper installation will give you thousands of light tight exposures.
