"Sure enough the outer bolt on the left hinge
plate had failed and this allowed the top to move back slightly and
bind up the rear latch"
Error in the write up. The top moved forward opening a gap between
the hinge plate, spacer, and top frame. As Dave points out the gas
struts are forcing the top forward when it is closed. Of course the
failure of one bolt greatly increases the load on the other.
