Kelly, I can't really be sure with out a top view but I think you need
a diagonal and a lateral tube tying both triangles together above the
engine. They don't have to be 3/4 dia.. Half inch or 5/8 .049 wall would 
work fine for this purpose as they would be fairly short and buckling
should not be a factor. The lateral tube could also be a 3/4 dia. 
bent tube if a straight tube is not possible. Have you made a model and 
applied a torque or lateral force to those two upper rubber mounts?

Looks like you have plenty of room under the engine for a large radiator.
