GENERAL INFORMATION
MODEL LINE UP
The 1968 Truck model line up consists of 441 models
on 39 wheelbases. The 104-inch wheelbase formerly
offered in 3/4- and 1-Ton Forward Control Chassis
applications has been deleted and the new 116-inch
wheelbase application has been added.
Seventy-three models are deleted for 1968. These
deleted units comprise of all Windshield Cowls, formerly
offered in Series 10 through 60; all Round-Front Step-
Vans, Square-Front Step-Vans, and Forward Control
Chassis with I-beam front suspension, formerly offered
in Series 20 and 30; all Tilt-Cabs with the Detroit
Diesel 3-53N engine, formerly offered in Series TT40;
and all Tilt-Cabs with the Truck D478 engine, formerly
offered in Series TG60.
Twenty-seven models are new to the line-up. These are
Forward Control units in Series 20 and 30 featuring new
chassis with independent front suspension. The new panel
and new suburban trucks introduced as 1967 interim
vehicles are not included as new in the 1968 line-up.
With the introduction of the new Series 20 and 30
Forward Control models, the Round-Front Step-Van con­
figuration is discontinued. Square-Front Step-Vans all
have new bodies; the 125-inch wheelbase is retained and
the 137-inch wheelbase is replaced with a new wheelbase
of 133 inches. Forward Control Chassis also are con­
tinued. In these applications, the 104-inch wheelbase is
deleted; the 125-inch wheelbase is retained; the 137-inch
wheelbase is replaced with a new wheelbase of 133
inches; and a new 157-inch wheelbase is introduced for
the accommodation of 14-foot bodies.

bering system does not change for 1968 Truck model

the left door hinge pillar on Conventional and L.D.F.C.
models, on the upper left hand side of dash panel on cowl
models, and on the steering column on Forward Control
models. On Tilt cab models (fig. 2) the serial number
and GVW plates are located on the left door hinge pillar.
UNIT AND SERIAL NUMBER LOCATIONS
For the convenience of service technicians and engi­
neers when writing up certain business papers such as
L.&M.R.’ s, Product Information Reports, or reporting
product failures in any way, the location of the various
unit numbers have been indicated. These unit numbers
and their prefix or suffix are necessary on these papers
for various reasons - such as accounting, follow-up on
production, etc.
