Go figure. I was just about to start a topic on this very subject.
My 46 1.5 ton has only the lock on pass side.
I checked, and the mech will not fit/work on the driver side without some major modification.
I am about 1 week from wet sanding/painting these doors and would LOVE to have a lock on the drivers side.
I'm guessing no aftermarket suppliers offer this option?
