The 1968-72 Pontiac A body
(Tempest,Lemans,GTO) Clutch Bellcrank is
a multi-piece unit made up of the 9792271 Countershaft,
9791016 Link, 9797165 Lever assembly, (2) 9791017 Pins,
(2) 3702807 Washers and (2) Cotter pins. The Engine side
is attached using part # 9427314 bolt, going through
part # 9791018 bearing (bushing) in the lever
with a 3702807 washer on each side of the bearing.
9792271 Countershaft
The Pontiac Parts Catalog calls this the Counter shaft.
9797165 Lever
The lever has both the 5/16" lower push rod
hole and a nearly 3/4" hole for part # 9791018
bearing. This lever has two "ears" with approximately
1/2" holes in each for pin part # 9791017 to pass through
and allows attachment of part # 979016 link. On the
lower portion of this part is a hole for the anti-rattle spring.
This part number is discontinued.
9791016 Link
This part is aptly named a link as it looks just like a three
sided chain repair link and is used to link the countershaft
to the lever via two pins. This part number is discontinued.
9791017
There are two of these link pins used on this equalizer.
They are approximately 1/2" diameter with an overall
length of 2", a 5/8" diameter head and a hole for a
cotter pin. This part number is discontinued.
3702807 Washer
This parts catalog calls for a 1/2" x 7/8" x 1/16" washer.
This washer goes under the cotter pin on both pins and
is also used on both sides of the part # 9791018 bearing.
This part # may still available from GM.
9427314 Bolt
This bolt has a 12 point head with a C in the middle
of three dashes (grade 5).It has 1 1/2" of thread
and a rounded chamfer on the bottom of the head.
This part number is discontinued.
9791018 Bearing
This part is more of a spacer that allows the "165"
lever to swivel. The used original I have has an
outside diameter of 0.685, an inside diameter
of 0.513 and is 0.715 long.

These inner and outer nylon seats act as a bearing
"race" that allows ball stud movement.

The frame side ball stud works like a knuckle joint
that compensates for engine movement.

fits in a groove in the tube Z-Bar.
This holds the cup, 2 seats and the ball stud together.

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, and when possible model specific assembly manuals.
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!
