No body mounts on first or second generation Nova/Chevy II's. The frame is welded to the rear of the car and there is no middle frame in the car. You can put subframe connectors in. The front frame bolts to the firewall and goes forward. The radiator support sandwiches over the front frame horn and is riveted from the factory. It is part of the front inner fender "doghouse" that bolts to the fire wall.
