67 Barracuda door latch assembly

Heres a thread with some explanation, I was surprised as well that there are differences.
[Found!] - RH Door latch mechanism for 69 Cuda
I can't imagine what the difference would be, but Classic Industries lists one for 1968 only. Don't know what the difference between a 67, 68 and 69 would be.
