Cone type (Auburn) was a standard option in the General Motors world at some point like mid 80's and on.
To the best of my knowledge, GM used the Auburn unit in cars with the 7.5"/ 7.6" 10-bolt (B, F, and G-bodies).
Chevy S10s with the "little 10-bolt" as it can be known (GM had A LOT of "10-bolt" axles over the years)had the "Gov-Lock" limited slip unit with a centrifugal weight that locked when the difference in wheel speeds was over a certain speed.
They stopped using it in 1998, when they updated the F-body and went to a Torsen differential.
The trucks still use the Gov-Lock differential to this day.
