#384239
General Motors Part Number 384239 Clutch Pedal Push Rod Seal

Used Seal
Pictures and descriptions are from a used seal
pulled from a 1964 Chevelle. And I believe this
is the part # 384239 and not the part # 9776826.

Inside
This is the side the part # 384457 retainer goes.

Bellows Type ?
The parts catalogs differentiate the part # 384239
(this one) from the part # 9776826 by noting the
part # 9776826 as being a bellows type seal.
In the picture you can see three "bellows style"
rings as apposed to the two on the # 9776826
seal. Also this part has an extra hole for attachment.

Measurement
The base is approximately 3 1/2" at it's widest
and it's "bellows are about 2" in diameter.

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, 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!
