around the piston. These shock absorbers provide
efficient and constant damping control because oil
is separated from air in the reservoir, which
eliminates aeration of oil and prevents lag. Sep-
aration is accomplished by entrapping the " a i r "
in a nylon envelope.
The front shock absorbers are positioned in the
center of the coil springs and are attached at the
upper ends to the spring seat towers. The lower
ends are attached to the lower suspension arms by
pivot bolts that go through the arms and the lower
shock mount sleeves.
The same type of shock absorbers are used on
all series cars. Individual valving, however, is
provided for Seventy-Five series cars and the
commercial chassis.

(Except Commerical Chassis)
The front ends of the lower control links are
attached to brackets that are riveted to the num-
ber 4 body brackets on 60 and 62 series cars.
Four bolts are used to attach the brackets on 75
series cars. The rear ends of the lower control
links are attached to brackets on the axle housing.
Rubber bushings are used at both front and rear
mounts.
The two front arms of the upper control yoke
have one piece flanged rubber bushings. The arms
are attached to mounting plates that are welded to
the number 4 frame cross member just forward of
the rear axle. To permit movement of the axle as
the rear wheels move up and down over irregular-
ities in the road, a spherical joint is used in the
axle end of the upper control yoke. The upper yoke
