possible metal-to-metal contact which would
cause squeaks. Check that clearance at fre-

thick. See figure 12-20.
2. If the required clearance does not exist at
.
all points, loosen the fender support bracket to
cowl bracket bolts and fender rail to fender
rear skirt bolts. Shift the rear end of fender in
or out as required to obtain uniform clearance,
then securely tighten all bolts after proper
adjustment is obtained.
3. On 1948 models where it is necessary to
move the fender up or down so far that hood
alignment is affected, it may be better to shift
the fender extension. The fender extension may
be shifted by loosening the bolts which attach
the extension support brackets to door panel.
These are accessible through opening along
bottom of extension.
4. After moving the fender in or out, recheck
hood hinge pilot pin alignment with hole in pilot
plate and re-adjust hood hinges as
required.

To prevent hood panel flutter and noise
it is essential that the panel has firm bearing
against the rubber bumpers provided for sup-
port, in addition to proper alignment and ad-
justment previously described. On 1948 models,
it is also essential that the hood hinges have
firm support on the bumpers installed on the
hinge plates. On 1949 Series 50-70, the rubber
bumpers must be installed in hinges and hinge
must have firm support on these bumpers in
contact with the stop screws located under
hinges. The flat head rubber bumpers in fend-
ers along the sides of hood opening are primar-
ily "safety" bu
mpers;
it is not intended that
hood should necessarily contact these bu
mpers.
2. The rear end of hood panel must have
firm contact with the rubber lacing attached
to cowl ledge. This lacing contains small
cylin-
drical bumpers which have pointed and grooved
lower ends to engage in holes in cowl ledge.
The bumpers must be securely attached and
sealed at the holes in cowl, to prevent leakage
of water into front compartment of body.
3. If cowl ledge lacing is loose, coat cowl and
lower side of lacing at bumpers with weather-
strip cement and let dry until tacky. Install
cowl ledge lacing bumpers by inserting a small
punch with rounded end in holes in top and
pressing pointed lower ends of bumpers through
hole in cowl until bumpers are held by groove
in lower
ends.
If
cowl is low in spots so that
hood panel does not bear on lacing bumpers,
raise low spots by bumping or prying upward
on cowl metal.
4. On 1948 models, the rear end of hood
panel must also have firm bearing on the rub-
ber covered metal bumpers installed on cowl.
The ends of these metal bumpers may be bent
upward as requird to provide firm support.
5. Occasionally it may be necessary to install
extra rubber bumpers on the cowl at the cor-
ners to support hood panel and prevent flutter.
If
extra bumpers are required, drill or pierce
cowl metal and install bumper No. 1326411
with round head metal screw No. 144753.
6. Any adjustment made to cowl ledge lacing
may make it advisable to recheck the bumpers
located on the hinge plates (1948) or stop
screws under hinges (1949) and readjust as
required to furnish firm support for the hinges
and hood.
7. Felt insulating pads should be located be-
tween hood top panel and the rear reinforce-
ment on each side just above the bend in rein-
forcement. If these pads are missing, install
new pads, using trim cement to hold pads in
place. One pad folded double is usually required
at each point, but an additional pad may be re-
quired to support hood panel and prevent flut-
ter. Do not install too much material or jam it
in so tightly that hood panel is bulged upward.
IMPORTANT :
After any work on front end
sheet metal assembly which changes fender
position, be sure to check aiming of headlamps
as described in paragraph 10-55.
