[Fot] Motor mounts, round or square?

I use the round ones, but I also have the Torque Reaction Arm in place.  This 
is an OEM part used on the TR4. 

It limits the travel of the engine when going from extreme braking to full 
throttle.  There is absolutely no question that it does, as I removed mine to 
reverse engineer this part to produce it.  The result was bent velocity stacks 
at the next outing.

Subsequently, I think it also reduces the stress on the rear tranny mount.

If anyone needs one, I have a few on the shelf.
