First picture shows the complete assembly in place. The shaft with the weight and indicators on it, prevent the flat piece from lifting the rod assembly unless the indicator is placed in the "to car" position. Otherwise it simply hangs down and prevents the flat channel part from rising when the lever is pulled down from outside the skins. That lever is rather short, just as pictured and protrudes thru the skins.
Second picture is a closeup of the indicator assembly and the spring loaded shaft.
Third picture shows me moving the weight back and out of the way in order to be able to pull the outer lever down.
Hope this helps.---KEVIN
