Ron, I am at the stage where I have to install the radiator, on reading your message it looks like I have to first hook the rings onto the hooks on the sides of the radiator bay and then pull them back over the hooks on the radiator. I tried doing it the other way, meaning installing the rings on the radiator first and then on the hooks on the sides of the bay but was not successful for some reason the radiator kept popping out of its slots.
