I believe there was a torque brace on the old blazers as well that bolted to the side of the transfer case somehow. it was to keep the engine from rolling out of the engine mounts under hard loads etc
did some quick google work and found this thread from this site. it shows the torque mount and how it is mounted. its an old thread but still available. have you seen something like this in your box of goodies?
