#3765372 60-72 Truck, Blazer
General Motors Part Number 3765372 Clutch Release Fork
1960-72 Truck Fork
This cast iron clutch release fork was used on
all most all truck applications from 1960-72.
Heavy trucks used a similar fork with a larger
ball stud seat and retaining spring.
This side goes toward the transmission.
The number cast into this fork is 3765374. But
the part number is 3765372.
Throwout Bearing End
This fork has elongated tips that ride in the throw
out bearing. On a new fork these are elongated
on the pressure plate side.
Ball Stud Socket
This fork can only be used with the correct size
and shape ball stud, GM part #3725240
(Our part #388) and the correct retainer, GM
Beware of reproduction forks that aren't
drilled deep enough and won't allow the ball stud
Push Rod End
The clutch fork push rod end has 2 slotted holes.
Use the one that is best for rod alignment. The rod
must have GM part #3795322 (Our part #289)
nut attached. The clutch fork return spring is
attached to one of these holes.
This fork came sealed in this paper and plastic
wrapper, with the pat # on it.

Most parts that I describe and picture have identification on or with them, others I can identify from other sources and deduction (educated guess).
Factory correct applications are your responsibility. GM made part and part # changes with no rhyme but a reason (no production interruptions at any cost).
Applications 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!
