I have a 67 bird had a 326 so it also had a flat hood I got a 400 hood from a friends 69 I remembered reading that the latches were different somehow so i also took his latch temporarily But I got it home and his 69 hood latched just fine with my 67 latch i inspected the 2 latches a little and i think i see the differences but dont see how that would make it not work
