GENERAL INFORMATION
0- 5
CAUTION : If
the six inch length wood block
is not installed, the towing chain could sever
the fuel line on the engine front crossmem-
ber .
A wood spacer block assembly should be placed
under the front crossmember (See figure 10) to re-
lieve some of the load from the energy absorbers and
bumper . This spacer block assembly should be di-
mensioned, constructed of hardwood, and bolted
together with three thru-bolts as shown in Figure 11 .
Raising front of vehicle so front wheels are four
inches off the ground will provide about five-inch
ground clearance at the rear when towing . Separate
safety chains should be attached to lower control
arms .
TOWING AT REAR
It is not recommended that vehicle be towed with
the rear raised as this could result in suspension or
crossmember damage .
