Body Mounting
New product improvements are introduced throughout
the entire truck line, including side marker lights or re ­
flectors for all models, identification and clearance lights
for all vehicles over 80 inches wide, and backup lights for
all Series 10-80 Chassis-Cabs.
In addition to extensive model realignment in 1968,
which includes the discontinuance of the round-front Step
Van units and redesigned P-20 and 30 models, all Wind­
shield Cowl and Series TT40 models are eliminated and
Series TG60 models are replaced with new models in the
TG70 Series.
Other new features include side marker lights or re ­
flectors for all models, identification and clearance lights
for Series 20 and 30 Step Vans, and standard equipment
heaters and defrosters for all models.
The basic cab is used on Models 10-60, with reinforce­
ments for heavier duty usage.
BODY MOUNTING
Body mounting is basically unchanged for 1968. Note
sequence of mounting attachments in Figures 2, 3 and 4.
BODY SEALING
Cab construction details showing location and applica­
tion of sealing compound and undercoating are shown in
Figures 5, 6 and 7. In servicing complete panels or only
a portion of a particular section it is helpful to know
where the panel is sealed.
Locating Dust and Water Leaks
A quick method for locating many air and water leaks
at windshield, backglass, bolt holes, weatherstripping and
joints is as follows:
Close all windows and vents, turn air conditioning or
heater blower motor to high position and outside air and
close doors. Run water over suspected leak area in a
small controllable stream and observe area for pressure
bubbles.
An alternate method for locating leaks is as follows:
.87 (WITH FREE CUSHION &
SHIM, BEFORE CAB DROP)
C-M-SA 40-50-60 \ C-KA 10-20, CA-30
NOTE: Line up flat side of
cushion asm. With the
closest body bracket wall.
