84 should have the stud for a lock as far as I know the doors didn't change until the TJ, which uses kind of a loop, the 1/2 doors all have the paddle latch and were available in 87, 87 took a different upper and didn't have a lock. but other wise are the same. I have a couple of sets of each and and have just added the strip if I didn't have a set of the early uppers
