Sorry to hijack this thread but to expand this subject a little I want to know where on the housing the stamped letter code is that indicates the gear ratio?

"Well I'll Be" as Gomer would say. I always thought (and was told) that it was on the flat pad
on the actual housing. I have a spare rear end that has a partial letter stamped on the pad. I'll
have to check the cover. Thanks for that info billd

I've looked and looked but can't see any marks.  It's a twin grip thats in a 69 Javelin that was one of the Aussie assembled ones and is therefore right hand drive.
 
Just explaining that in case they did things differently in Aussie, however I'd have thought that the diffs would have shipped ex USA assembled.
 
Any other ideas?

Here's the inspection mark on the other flat pad, but the right one had nothing at all, you can see it in the pic below this one with the inspection mark.

through the years i have found stamps on the cover and housing. i think it just depended on what they hit that time with the stamp.
usually left side.

That's a great picture and explanation.  I've been under my car many times looking for the stamp with no luck.  I'll check the diff cover...I had no idea it could end up there too.  Mysteries of the world - solved.

Interesting,  Code on my 79 AMX says 2.87TG, but never have found the code on my Gremlin, and it does not have TG.

The code on my '70 is on the left side, but under the diff cover flange, so the cover has to come off to see it.
