I am not near my parts book - wondering if someone has the Cat part number for the rad core - this is the early style rad with the heavy cast tanks and side supports. Two of my cats have L&M Radiator "Mesabi" style rads with the tube ends mounted in rubber grommets. I need the cat # to see if L&M can find a cross reference in their records. If anyone has an L&M part number for the early D8 this would be great!
