to the person who asked about an american made aluminum radiator , I am so sorry for taking so long but I could not locate my paperwork for the one I bought. However , if it can help you or someone else , I found a site on Ebay still selling the 3 row (for extra cooling) from California. Ebay item # is 394109690251 cost is $668 with free S/H. dsn_cooling (autocooling) Worley.
