So this diff has been messed with, (probably to be used for drag racing) as you know, and it appears I have a cone style sure grip that does not utilize a thrust button. OR is it possible the thrust block can turn 90* so I cant see the hole where the button inserts? or, do I have my anatomy incorrect and the thrust block does not house the button

No; the T-block cannot turn, and the shiny ends are made to be working surfaces. I have never seen a worn-out one.

The clutch type has 4 pinions on two crosspins that interlock in the center. This kind has buttons as there is no way that I can see for it to work otherwise. This system allows the clutch actuation mechanism to work independently from the Thrust mechanism.
