#3746615
1957 Chevrolet Passenger Car Z-Bar
The General Motors part number 3746615 differs
from the 55 and 56 Chevy Z-bars in that the angle
of the lever is less. This is why the upper clutch
push rod is longer than the earlier years.
1957 Chevy Equalizer
I have had three New Old Stock levers and all of
them came with the part number 3716811 clutch
rod bushing installed. This part appears to be
galvanize coated.

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 and part numbers 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 won’t be sorry).
This is a fun and interesting part of the hobby!
