I'm trying to replace the original 4 blade fan on a 235ci with a flex fan but can't seem to find one with a hole larger than 5/8" for the shaft. Does anybody know of a source for these or do you have to modify one of these fans. I've checked out several local and online parts but no luck. Places like Chevy Duty and American classic have fans but are all original. Thanks for the help. :confused:
