I have YJ halfdoors on my TJ. Strike plates can be replaced with washers and the YJ strikes you can buy from quadratec for like 8$ each. I have TJ half door uppers, you have to cut one post to be able to use them. You will need to weld the third post back on at a slightly different location, but you can run the tops without doing that. They just pop out if it's gusty on the highway, not ideal
