Placing the Transmission Jack
Third, install the Squangle Bars as shown. Be sure the trans jack plate is lifting the trans slightly, then tighten the pinch bolt joints.

The adapter is very stable even on heavy and awkward loads like this transmission transfer case assembly from a Ford truck.
Second, remove the transmission mount and bolt the L-Blocks of the adapter in its place.
