putting door lock on drivers side door (AD)

[msaintg]

hey guys, I read somewhere that I should be able to add a door lock to my drivers side door. I read that the stock latch assemblies were the same. Well, I was trying to do just that, but found out that the latches are different. There is a 'cam' piece with a groove for the lock on the passenger side that is NOT on the drivers side latch. And the mounting plate is wider on the passenger side than the drivers side, so I can not just add the cam piece to the drivers side latch. Is there some way of modifying the latch that I don't know about? ..... and if you are only going to put one lock on a truck.... why did they put in on the passenger door? stupid, I tell ya.
thanks, Mike
