I just read your post again. If you mean the true dogbone on top of the engine, my earlier reply is right.
If you mean the mount at the base of the engine/transmission at the back, yes, you DO have to support the drivetrain.
The dogbone I've outlined in red below is the one that is not holding the engine up -- only keeping the top of the engine from rotating toward and away from you.
