The build sheet for my 69, 428, 9/19/68 built Sportroof calls for a C9OE-G fan. That is the engineering number. I would like to know what markings would be on the fan body and blades. This fan was also used on the Mercury car line, Possibly, the big block cyclone, marauder and Cougar. So if a mustang or a mercury what would the part numbers be ? Any help, Thanks, Brian
