The stiff slopes are corrected at the same time with the valleys

TOOL EQUIPMENT
The proper alignment and repair of doors, cowls, tops,
luggage compartments, and inner body construction can-
not be accomplished without a complete, modern set of
the proper body repair tools for reaching all of the open
and closed areas in the modern automobile body.
Body jacks, which are the backbone of all heavy body
repair, are available in a variety of styles and sizes.
FIGURE 53
Past experience in the repair of steel bodies has definitely
established the fact that major body damage requires the
application of more than one body jack. Unless pressure
is applied simultaneously to direct and indirect damage,
further damage, stretched metal, and excessive metal
finishing are the results.
Hydraulic body jacks should be light in weight for easy
maneuverability.
Jacks have to be moved frequently in order to apply
pressure at the proper places and good workmanship
requires ease of handling.
BODY MANUAL
FIGURE 54
A power body jack must be adaptable for reaching all areas in the
body -- behind inner reinforcements, crowned panels, door head-
ers, and body pillars. It must be constructed to offer easy, simple
operation by one man in any position in the body.
FIGURE 55
Fittings and attachments are a large part of the answer to the jack
that will go where you want it and how you want it. Fittings must
have quick change features with instant wide-range adjustment
for each jack. All fittings should be interchangeable.
FIGURE 56
A hydraulic spreader or wedge, Figure 56, is readily adapted to
getting into close, narrow places (closes to approximately
1-1/2" at the working end).
