Left: Previous version
Right: New version

Front handles with an integral stiffener (arrow) will
be installed in the future. The previous stiffener,
which was screwed to the front handles, has been
deleted. This modification necessitates different
screws. The present IS-P6 x 32.5 spline socket
head screws will be replaced by the shorter IS-
P6 x 21.5 screws.
To ease replacement, the new screws will be
supplied with the replacement front handles (see
summary).
