My research show this NOS 633734 upper fan pulley fits most Dodge, Chrysler, Plymouth, Desoto cars and Dodge trucks from 1932-50 with six and eight cylinder engines. My research also shows this part number to be the same as 602044 and 683647. Please research to confirm my information before bidding and email if you have questions or need additional information. I guarantee the part number 633374 is correct, but not the applications or superceded part numbers. Thanks for looking
