Bob Drake has a complete kit for the 39 ford car that has all the hardware, new latches, and locks to add a lock on the driver side for a 39 ford car. Not sur if it fits a truck. Try www.bobdrake.com or call 1-800-221-3673. I have bought quite a bit of parts from them and they are good to deal with.
