#462607 78-87 A & G Bodies
General Motors Part # 462607/14007356
While
most GM clutch release forks will physically
fit in any General Motors bellhousing. The "356"
fork is specific to 1978-87 A and G body cars an
their special bells.See 462606 or 464697. Since
there wasn't many of these cars manufactured with
manual shift, and the fact that these are "wear items',
the original forks are very hard to come by. Because
of their unusual shape I personally felt they would
never be reproduced. WRONG, due to the popularity
of turning the 78-87 A & G bodies into Muscle cars,
they are now reproduced. The early (1978-79) fork
is part number 462607. This was replaced by part
number 14007356. Both parts fit the "G" body
bellhousings, with the "607" 1st design fork having
a straighter bend than the "356" fork.

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!
