Always place a rubber mat or other suitable material be-
tween the bumper and the tow chains or cables.
For front end lifting, place chains or cables around the
ends of the frame side rails at both sides.
All models can be towed short distances without discon-
necting the propeller shaft except in cases where the key
is not available to unlock the steering column and trans-
mission.Insuch a case,thepropeller shaft must be discon-
nected and the car towed from the front. Where the
transmission or propeller shaft has possibly been subject
to failure or damage, the propeller shaft must be discon-
nectedfrom thedifferential andwired tothetailpipeorcar
must be towed with rear wheels off the ground. If the
propeller shaft is disconnected and the "U" joint bearing
retaining strap is broken, wrap tape around the bearing
capsto prevent loss. When towing with therear wheels off
the ground, the steering wheel must be centered and held
in position by a steering wheel holding clamp or by tying
it to the window division channel. Tire to ground clear-
ance should not exceed

one (1) through five (9, stamped on its side. Before the
lock cylinder may be coded, the correct code must be
determined.If the numbered blank in the key head has not
been removed, determine the code by consulting the lock
manufacturer's code book. Should the blank be missing,
proceed as follows:
1. Place the key on the silhouette in Fig.
0- 15, aligning
the key with the outline as accurately as possible.
2. Starting at the base of the key blade, determine the
lowest level visible in position No.

3. Determine the lowest visible level for the remaining
five positions. As each tumbler level is determined,
write that number in the blank space above the posi-
tion numbers.
After the key code has been determined, the correct tum-
blers should be installed as follows:
1. Beginningwith slot next to head of cylinder (number
