The Ford Barn

I'm sure this has been hashed out before but if I read it, it didn't sink in. I'm building an A-V8 using a 39 rear. Looking to see what others have done, I see a lot of people relocated their radius rods out to the frame. I'm doing this on the front based on the theory that the Ford front axle can twist slightly as it travels through an arc. The rear axle is obviously not going to do this. In my mind, it seems that in some extreme conditions on the suspension, such as hard cornering, is going to put a lot of stress on the radius rods or their mounting points.

I'm guessing locating the radius rods to the frame would be OK if one was using an open rear as the U-joints and yoke would allow some twist in the rear. But a torque tube ties the rear axle into a straight up and down movement. It seems that splitting the rear radius rods, some equipment is going to get torn up or someone is going to get hurt. Am I right or am I overthinking this?
