With all due respect, if I had a '58 T-bird, I would get a torch and cut those clappers off
completely. All they accomplish is to restrict freedom of motion which is what you don't want. Furthermore, they transfer torque to the upper control arms! Again, something you don't want.
So for now, you have your proof. This explains why no other trailing arm suspension uses 'clappers', across all car lines and models. - Dave
