Toyota LSD / differential codes

Toyota Axle Website: http://www.norbie.net/toyotaaxle/

 

As an example of how to decipher Toyota axle codes:

 

The '80 Supra from which I grabbed the solid rear axle has code "F312" which corresponds to:

a 7.5" Ring Gear, a 3.909 gear ratio, and 2 pinions with no LSD.
