New commercial mount for 2004R transmission
I can't see clearly in the pics, but if the whole upper mount is welded to the floor (factory only had tack welds) it would transfer a good bit of the flexing to the body. That would help considerably. The new upper mount would also have to be fully welded to the factory cross member, I know it's welded on three sides but I can't see how you would weld on top??/
The basic design looks good, it's just a matter of transferring the "twisting" motion to a solid part of the body/frame.
