Axle identifying help please

[caljon88]

Can anyone help with identifying what my rear axle and gearing is? The picture maybe is CCA 0929 B which is a 3.08:1 10 bolt. Could the picture show a CGA which is 2.56:1 10 bolt for the 350? I originally have a 350. The second letter isn't clear or stamped entirely.

It also looks like my ring gear is positraction which could have been changed out at some point I guess.

Looks like CCA, but if it's now a posi then the gears most likely have been changed. Looks like you have some ID numbers on your gear. Count the turn of the wheel to 1 full turn of the driveline will tell you the ratio

The "two" C's don't look the same though, the bottom loop comes up higher than the first one. Looks like it could be a badly stamp G maybe? You can see it says the 1 GM 3xxx.... Not sure if that means posi or not.
