Interior locking mechanism
 

Does anyone know the part number or where I can source both driver and passenger side lock mechanisms?(see photo)

I recently purchased an 82 SC hot rod build with RS door cards but they removed the interior lock/unlock knobs as well as the electronic lock unlock button so there is no way for me to unlock the doors from the inside once they are locked other then using the key to unlock the door from the outside. They modified the original mechanism to remove the square female bolt receiver.

Any chance they backdated the lock pin in the garnish rail, such that you can pull up on it and unlock?
