General Motors Part Number 9778882 Bellhousing
The Buick,Oldsmobile,Pontiac "882" is an all
aluminum Bellhousing. These clutch and flywheel
assembly covers were manufactured for multiple
applications, as evidenced by two starter housings
and dual transmission mounting bolt patterns.
In 1965 General Motors used Dearborn built
(Ford) 3 speeds as a heavy duty option to the
Muncie 3 and 4 speed trans on some models.
Instead of casting different bells they made these
more universal.

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!
