Not really . . . it's attached to the core support using 3 5/16" bolts on each side, screwing into nutserts, and the weight is supported and the bottom, where the radiator sits on a ledge . . . moving it out a half inch would cause all the weight to have to be supported by those nutserts, and would require longer bolts, which would put even more stress on them . . .That's a little close. Can you move your radiator out 1/2" with spacers?
