Hs{Lord Ernest Hives - Chair}/Les re SpectreCodename for Phantom III Bumper Test. We should be/glad if you would couple up the radiator to the dash and frame with the bonnet side strips when running this test, as these pieces constitute part of the anchorage for the radiator, and without them it is likely that the top anchorage will fracture.
