T-5 in a Camaro/S-10, apples.
T-5 in an AD, oranges.
Engine mount arrangements are vastly different.
As far as the 3rd crossmember in an AD, that was for the torque tube ball, not for supporting any transmission weight. One can ascertain that from looking at the frail design of that particular mount/bracket.
