My 33 truck has non-locking door handles. I would like to convert to locking handles. My best option I've seen so far is from the Filling Station. They have a locking door handle for cars for that era (only the passenger side). You have to lock the driver side from the inside, then slide over and exit out the passenger side. I would need to do some modifications for this, but not sure what. Anyone done a conversion to locking doors on 1930's era trucks, with that era style handles?
