Yes...I did and put 2 on mine with engine plates. One on each side of the block going from one motor mount hole on the block to the frame rail. Prevents foward/back movement of the drive train.

To clarify what Jeff said the limiter he is referring to is made of tubing and the end that mounts to the frame rail should be mounted on the frame rail right behind the motor plate mount.

So this tube runs mostly front on the frame to back on the mount hole to keep the engine from oil canning the plates, which are weakest for forward and back flex and plenty strong for twisting?

If you had a midplate and front block plate ONLY then the motor would spring forward and backward like a banjo string. The only thing that would be keeping the motor from moving too far back would be the drive shaft bottoming out against the output shaft of the trans. Using only a poly bushing will not be adequate either.

You can also use strut rods going forward of the motor that are tied to a crossbar somewhere in front of the motor. We've made plates that bolt to the holes that would normally hold the motor mounts then attached the rods to these plates.

Sounds like people could use a plate that has a lip welded on. My chassis car only had a front plate and a normal poly transmission mount. Never had an issue I knew about.
