That's the later design,& only one being reproduced and was made to fit the 4 core Radiator originaly.
The #165 was specific to the 3 core BB radiator,in that it has a lip going into the core to meet flush.The #914 will work,but if the car has a 3 core Rad. you will see daylight where you shouldn't.Some of the #165 shrouds were shaved of this lip to fit the 4 core on the line,until they tooled up for the New #653 4 core shroud,which is what the #914 copies crudely today.
