Default 1977 C3 differentials

Do all 1977 C3's have positraction?

I'm pretty sure all did come with positraction, but there was an option G95 which was a positraction axle with a different ratio, most likely a 2.92 or 3.11 or 3.36 for better mileage. Mine has a 3.55 in the L-82.

2.92 or 3.11? I don't think so.
