The door lock cylinders that some sources sell are for the independent locks so they are different. I haven't looked and the integral to door handle locks on those that are reproduced that way. They are reproduction so may not be all that close to the old tech Ford door handles. It would take a good bit of research to see if any of the later Ford door handles may be similar. 32phil over on the Early V8 side may know more about compatibility than anyone else I'm familiar with. He cuts keys for some of the later Fords.
