I installed these "G" body chassis supports that go from the engine crossmember to the frame horns on my "66 Tempest Custom wagon. These, along with the UMI chassis brace that bolts behind the front stabilizer bar frame mounts, really stiffens up the front end. Car feels solid as a rock going over bumps and around corners. SC & C makes a brace that does what this does together. If I wouldn't have already had the parts, I would have went with their brace. Really worth checking out it you like your car to handle, and ride well.
