If your going to go to the trouble of installing a front motor plate, it's a good idea to also install a mid plate between the motor & trans at the same time. Using both plates at the same time reduces the load on the front motor plate, and spreads that load over a much larger area.
An engine/trans combo mounted with plates, (either front plate only, or front & mid plates), should still use a flexible trans tail shaft mount, (rubber or urethane). This is because all chassis flex to some degree no matter how many bars you add, (from a FOX body with only a 6 point bar, to a full chassis 'moly door car, they all flex some), and the thin aluminum trans case doesn't need any twisting forces applied to the tail shaft, main case, or valve body. Along with the mounting plates, a set of travel limiters is a good idea.
If it's going to be a mostly street driven car, a good set of factory style rubber or urethane mounts might be a better idea than the plates.
