Need help to remove bindings from skis

I'm trying to figure out how to remove bindings from a set of skis. For the rear section, I see two screws for the front section, but can't figure out how the back of the rear binding piece is attached to the ski.

The bindings have 'MARKER' on them.

You did not mention the model name of the Markers.
I assume it is an old model so I will provide you with the procedures based on this assumption.

The rear unit has a plate with rail that is screwed to ski. There are 4 screws holding this plate. You muts "back off" rear binding by using the rear lower screw. The upper screw is for the DIN adjustment. Do not touch it!

Once rear unit is off, it is simple matter to take rear plate off. Note position of screws and place back in slots fro screws. Plug holes if you will use ski!

Careful with that Phillips screwdriver, it may "strip" your screw heads since you must use, POSIDRIVE screwdriver!

Forgot to tell you.

You are never "old" to ski, just better!

My wife gave me a T-shirt for Spring skiing ( very wild, very 60's shirt). It says, "Aged to perfection"
