Nope..   Gary's IS a C rear end..  although the C is partially obscured by an 'impact' wtih a rock or something in the past..?
(Bryan and Kurt finally convinced me there was a 'C' out there in front of the BU..)

Gotcha. I think I can barely see it now. That makes sense.

sorry just noticed this thread
Here is a pic of mine from a 08C ( August of 69) car.

Do you have the casting number and casting date from this rear?  Maybe I missed it in an earlier post?

I have a 860 C.B.U. rear end, casting is  September 6th of 1969 and axle stamped 9 16. I will try to post pics of the C.B.U. axle stamp tomorrow.

I was incorrect , my rear end is not a 860 casting it is a 341 casting with a CBU 9 16 tube date and a J 6 casting. I took pics but not sure how to post on this site. My TT has a 9 A date ( 1st week of September) so my rear end is a little late for my car. I see some fellow members on this post have good dates that would be correct for my car. I'm assuming the rear ends are under there cars but if not are any of you guys interested in selling or trading your rear end ?

Kurt would be able to answer better, but your axle stamped CBU0916 may be OK for your car.  

You can send pics to my email and I will post them if you want. Click on my username to get my contact info.

Ok Gary got me back under my car and I got the rest of the info. I have the 3969341 rear end, dated (I think ) G 25. So far it looks like the only one with 341 casting but still has just the 2 letter format.
There are a couple of other 08C guys on here ( Sonny, vellu, Jims69, and nick -Daytona Yellow 69 Z)

I just went through my correspondence with Jim, and his vin is a couple of hundred after mine and his rear end is the 3 letter format. Hopefully he will chime in with his info. So mine may be one of the last of the 2 letter format, and Jims may be one of the first for the 3 letter format.

Bullitt's 0815, without the C (but with the 341 rear), and Sarge's WITH the C, stamped 0820..  pretty well brackets the change to use of the 'C' (1970 format) to between the dates of 15 August and 20August 1969.   Bullitt's diff is the later casting number, but without the 'C', so that seems to imply that the two changes (C) and 341 casting, did not occurr simultaneously...

The rear end casting, and use of the 'C' in front of the diff app stamp are two more items to add to our list of intended 1970 changes that were applied to 'late 1969 extended production of Camaros and Corvettes.   I think it would be a good research report to itemize all the things that 'changed', as well as best known dates of change, for late production, and would be useful in the generation of an 'ultimate' Restoration and judging reference manual for Camaros.

Actually Jims69 will bracket it better, his car is about 197 after mine and his has the C. I sent him a message hopefully he can post the casting and date on his.

Wow..   197 cars is like a few hours, unless it's the end of one day/beginning of the next day production, OR with it being a new thing (stamping the C) in the differential plant, perhaps they just weren't consistent yet..?

We are getting closer on this.  When you post, make sure you include not only the casting number and casting date, but the COMPLETE data on the assembly stamp. That includes 2 or 3 letter code, date code, assembly plant and shift.  

And having pics to back up the data would be great.

Will get something written up when things are closer to final.

Thanks!
