A lot of streetrod/hotrod parts dealers sell SPAL and also Cooling Components Inc.. Walker Radiator sells CCI. Also direct from CCI at http://www.coolingcomponentsinc.us.com/ and Yogi's has both brands at http://www.yogisinc.com/

Your local streetrod shops should either have one or the other or be able to order them for you. Do an internet search on their names and you will probably find them and they can usually tell you who their distributors or sellers are. SPAL fans are widely sold.
