(*1) NOTE - A 2nd type design 1964-F85
V8 & J88 clutch pedal linkage was introduced
in 1964 production. ALL 1st design pparts have
been superseded by 2nd type parts for service.
When replacing any 1st design part it will be
necessary to use all the 2nd design parts in conjunction
to make proper installation. 2nd design parts are
listed in the following groups 0.787 lower rod
& swivel, 0.795 extension, 0.846 evtension,
0.852 equalizer and 0.854 upper rod.

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!
