Is it possible you have a 30-31 frame under a 28-29 body?? The radiator mounting area on the front cross member for a 30-31 frame is lower then a 28-28 frame. Did you mount the new rad. using the same pads or shims as the old rad?? This can be corrected by adding extra pads under the rad. mounts. Just a thought.
