You'll find the codes in the first section of the 1970 Chassis Service Manual on Wild About Cars:

Keep in mind you could order the anti-spin axle (option code G80) with a variety of differential ratios, ranging from 2.56 to 3.91 for 1970.

There should be a two-letter or a letter-number code on your passenger side axle tube. I've seen them facing either forward or aft, and sometimes right side up and sometimes upside down. With that code, you can determine what your differential ratio is and if it has the anti-spin axle (that is, unless someone has gone into the differential and changed it!).
