The above is a pic of the hinge piece on the movable part of
a translucent RV vent.

Got an new identical cover, and tried to replace it.

I'll be darned if I can figure out how to get this on.

If I hold it vertically, to clear the vent housing, the
hinge piece is rotated too far to slide on.

When the hinge is held so as to be able to slide on, it hits
the vent housing.
