61 Differential Codes

I have my wife's 61 in pieces all over the garage doing a frame off resto-moderation. I have been working on the frame, cleaning 48 years of, well you know what it looks like, and one thing I want to keep is the differential. I am trying to find what the codes for it are and haven't been able to locate anything on the net with the codes. It has the posi fill sticker on the drain plug, but it doesn't act like a posi. Most posis I am familiar with will spin both tires the same direction when you spin one. Non-posi either go in the opposite direction or only one turns and that is what this one does, which makes it confusing with the plug tab. THe codes are GM 24 H770 3725899. If anyone has any information, a source, or link to codes I would sure appreciate it.

Thanks!
