Champion Radiators

They all have 4 mounting locations, my point was that the lowers usually fit into a slot in the mounting ears. You install the lower bolts loosely, set the radiator down onto them, the install the upper bolts so you don’t have to hold the radiator up the whole time. Then you snug everything up. The lower mounts only clamp a little, they’re not tight circumferentially around the bolts because the bottom is open so the radiator can still shift around as the support flexes.
