You can install these three ways. Since my doors are taken apart and stripped down I mounted the locking mechanism inside the door. You can consider one of the following. Use the instructions and cut a area for the latch and mount the plate on top of the door skin (more for your already painted truck), or use the plate as a template to cut out that area from the door and weld the plate into the door.
NOT MADE IN CHINA, and they only work on the 53-56 Ford Trucks. On the instructions there is a number you can call for help.
This mod took me about a hour per door. Everything went very smoothly, it was a nice break from sanding and you felt good to see some progress made. I installed the door back on the truck and closed the door for the first time. It closed perfectly! There is a link to my YouTube page of the door being tested at the bottom on this post.
Please post your comments on your install. Or after installing them are they still working well for you?

I then mounted the door for a test fit and with little to no adjustment it shut perfectly. Really like these latches highly recommend them.
