You'll need to know the width of the radiator. Either 22" for non-factory a/c cars or 26" for factory a/c cars . . . or that's usually the situation as to radiator sizes in Chrysler products.
Does the car currently have a direct-drive fan or a fan clutch?
There was a 65 two pc shroud for sale on Facebook just the other day. I believe it was for sale by a member here. I think possibly it was @azblackhemi Chris from Arizona?
