This invention relates to motor vehicle bodies
and more particularly to an improved side wall
An object of the invention is to provide a light
weight hollow wall section preferably formed of
a pair of complementarysheet metal pressings
Other objects will become apparent from an
inspection of the accompanying drawings wherein
