These hoods will fit all 3 years but the hood latch area is different on the 67. You have to use a 67 hood latch on a 67 Hood and you can use a 68 or 69 hood latch on a 68 and 69 hood. If you use a 68 and 69 hood latch on a 67 hood you can't get the hood open (a big no no)! The area of a 67 hood latch area is flatter than a 68 and 69 hood latch area.
