908092
GM's part # 908092 Throw out bearing is long at 1 7/8" overall length.
This clutch release bearing was originally used on 6cyl. and lower horsepower V-8s,
because of the lower profile pressure plates used on these cars.
This may be the hot ticket for newer aftermarket performance clutch systems,
that utilize a lower profile pressure plate that makes clutch adjustment difficult.
NOTE: Check with your pressure plate manufacturer to see if this round bottom bearing is compatible.
Fork End
This is the lip that a clutch release fork fits under.
Pressure Plate End
The "092" bearing has a "rounded face" that contacts
the pressure plate fingers.
Diameter
Inside diameter is approximately 1 3/8" with a 1/4"
grease groove in the middle fork end O.D. is 2",
while the pressure plate side is about 2 7/8".
Length
The overall length is 1 7/8" with the standard 1/2"
groove, for fork attachment.

# CT22-1
I have a few of these new bearings and they all
have slightly different size boxes and lettering.
The # CT22-1 and # 908092 can be found in many
of the General Motors parts catalogs.

Disclaimer:
Factory correct applications are your responsibility. GM made part and part # changes with no rhyme but a reason (no production interruptions at any cost).
Application charts are for replacement parts that were available at the time of parts book printing.
My observations come from the parts I have in my collection or other reliable sources your parts may differ.
If Factory correctness is your goal, do more research, join car clubs,
forums and buy an assembly manual if one is available for your Project Car (you wont be sorry).
This is a fun and interesting part of the hobby!
