As of 1/11/21, US Legend Cars International will be mounting the current (“big”) radiator bracket on the bottom of the frame rails of the front clip.
This rule change will allow competitors in the field to mount both the “small” radiator and the “big” radiator to the bracket on the bottom of the frame rails of the front clip.
You can turn the bracket you currently have over, make your own or the factory one being used will soon be available for purchase through US Legend Cars International. The “body” of the radiator can be no lower than the bottom of the frame rails of the front clip.
