67 Cuda 5.7 Hemi Tranny Advice Needed

I would imagine it ties together the frame rails in the front. I'm putting a 5.7L and a 545RFE in my 73 duster with the RMS kit. I didn't feel right about taking that cross member out until I put in frame connectors, torque boxes, and US Car tool's front suspension stiffening kit...but I'm also crazy about not having the twists in the turns. I'm no structural engineer, but without some sort of stiffening, I would be hesitant to remove the whole cross member without help elsewhere.
