Thank you for the quick responded. It is in fact a 4 door car with suicide doors. As I learn more about the model and other info I will be sure to post it with my questions moving forward.
I suspect it is the square part in the door latch mechanism. I changed the handle from the passenger side and still same issue so the handle seems to be ok. Oddly the back door had a different length shaft. I will take it apart this when I have time and I will post it on the parts wanted section. If not available quickly I will do as you suggest and sacrifice the back door.
I also included a picture of the car in that is helpful to anyone.
