Champion Radiators

Core support flex is a known deal with these cars, so grommet mounting helps keep the radiator from flexing with the core support.

Yeah but the radiator mounting bolts don't need to be torqued to 50 ft/lbs. It just bolts at the top too, the bottom attachments it should just kinda sits on top of like the factory radiators did. That way you don't get a big corner to corner twisting action.
