Great info and a awesome article  Byron. Glad you could use a photo of mine.

Re-read it some more times. Now I know which fill plug to look for on my 68....Joe

Congratulations on a great report. Lots of good information for anyone trying to understand or work on a 67-69 Camaro rear drive axle. I do have a concern with the naming of the main components. It is my understanding that the housing you see when you look under the rear of car, that contains all the gears and bearings is called the "carrier'. The parts catalogue calls that housing "carrier and axle tube assembly. The housing inside that holds the differential gears is called the "differential case'. The differential case is available with limited slip [positraction] or conventional [open] components.

I thought the wording was right, but will check things over. Thanks for the feedback!

Nice work, Bryon.

Is "pinion yoke" used more commonly than "pinion flange"?

[bcmiller]

Yep. Say Propeller Shaft Pinion Flange and Deflector to some people and they might not understand. Pinion yoke is less technical, but more widely understood.

That is not the industry accepted use of the terms.
The differential carrier is that which carries the differential gears. Case is often used as an equivalent term.  https://en.wikipedia.org/wiki/Differential_(mechanical_device)

Some of the terminology confusion comes from the different designs used over the years!

For the Camaro 1st gen differentials, where the differential gears are 'assembled' into the entire case, the 'case' if the carriers.

For older chevys which had a 'chunk or pumkin' that removable chunk 'case' was the carrier.   Same with Ford 9' rears...

Congrats and Thanks to Bryon and others for the time researching and reporting this information.

The automotive industry terms for the two major drive axle components used in the 67-69 Camaro are:  "differential carrier" and "differential case". When ordering parts or diagnosing problems on the Camaro rear drive axle the "carrier and axle tube assembly" is usually stated as the "carrier". The component "differential case" is often abbreviated to "diff case". The incorrect use of these terms has caused much confusion when discussing many vehicles including 67-69 Camaro.

Can you please clarify if “l” or “H” was used for 1968 carrier date stamping? I heard that “I” was skipped in the alphabet.

Look through this thread at yenko.net. Post 12 has a shot of a 68 unit stamped "I"

“I” was used for year. And it’s calendar year.

I had one with “I” a while back but the post Mike mentioned was confirmation of its use.

Do you have data which conflicts with that?

Based on the report and supporting photos is it clear enough to understand?  I appreciate the feedback but you need to realize it’s impossible to please everyone.
