2 speed rearends

More Pics.
This is a copy of an article I found, I don't
know why the spelling is garbled.
The Streep was designed to fit directly into a 9 inch
as the pionion and overdrive together.
I am unable to post a picture of it.

It's the Dana-Spicer two-speed "Streep"
renr axle. This goody mokes it possible for the "Eiirmnntor"
to lead a double life. Developed by the Dana Corporation,
the two-speed oxle unit is 0 modificotion of the Spicer Model 53
oxle which incorporotes 011 overdrive ratio of .675 :1. This Dana-Spicer
two-speed design uses a standard axle that is extended approximately 5
inches over conventionol designs and enlarged to accommodate 0 countershaft.
Reference to the cutawoy diogrom reveols thalwhen the shift lever ond fork ale in
f
direct-drive position, octuotion of the shift lever rotates
the cam and compresses the spring ogainst the opposite foce
of the shift fork. The sliding clutch gear which is splined
(0 the input shaft rotates ot drrveshcjt speed. When engaged
with the mating clutch gear, that gear will rotote at
driveshoft speed. The disengaged clutch gear will rotote at
another speed as determined by the countershoft geor ratio.
When speed is reduced, the friction force becomes less and
allows the sliding clutch gear to move to the neutral position
between the two clutch gears. This neutral position
will allow the speed of the sliding clutch
gear to match slower speed of the splined
clutch gear so the teeth will align and complete
the shift. The major cam diameter,
being greater than that of the shift fork, will
remove the spring load. Thus, to shift, the
selector lever is moved to a position which
in turn applies a spring load to the sliding
clutch. The accelerator is adjusted to opproach
a "float" load. When the spring overcomes
the sliding clutch friction, the
clutch shifts to a neutral position. To complete
the shift, the engine speed must be
motched to the speed of the clutch geor to
be engaged. Since at this time the axle is
in neutral, adjustment of the occelerotor
will provide correct engine speed to sync
the two speeds and complete the shift. Some
ratcheting will develop until speeds ore
synced; however, the [aces ond teeth of the
clutch gears ore designed to take this obuso
